Bitcoin Forum

iOS is more secure than Android btw. If you want Android with better security get the new Blackberry Priv running Android thats been out recently.

Breadwallet ceo:

RVC: I've read that mobile wallets should only be used for pocket change. How much money can I safely keep on my phone at one time?

It's ironic, because many people don't realize that their smartphones are actually the most secure computing device they own, far more secure than desktop or laptop systems. It's wallets that can be accessed from the web or desktop that should really only be used for pocket change.

An iPhone uses the same techniques of app sandboxing and enforced code signatures that dedicated hardware wallets use. The phone is also hardware encrypted so your funds are strongly protected even if it's physically stolen. The US DOJ even complains publicly that the phones are too secure. Some people prefer to keep large amounts in paper wallets, but for someone who doesn't have a strong technical knowledge of bitcoin, misunderstanding how change addresses work can result in total loss, so they're not really suitable for the general public. There was recently a $1M dollar bounty offered for a remote jailbreak of iOS, and the winner ended up having to use an exploit in the chrome app, so if we assume markets are efficient, then in theory it should be safe to keep at least $1M in breadwallet (if you don't use chrome).

It's most likely the opposite. People have no idea how to keep their desktops/laptops secure and it is much worse then it comes to the mobile area where apps can have access to almost everything. Another problems would be apps that carry hard to remove exploits (tends to happen in android). It is not possible for a smartphone to be safer than a Linux machine solely dedicated for a wallet, running behind a hardware firewall.

The thing is that phones can be lost, robbed, broken more frequently than a Desktop. It is more a safety thing than a security thing I think.

Storing money on desktop is just a pain in the ass, Smarthphone is much easier to use and at times even more secure, even if you lose your phone you can recover it. Money on Smarthphone is the future.

i do not agree, it's like asking for the next thief on the station or where you want, to steal you all your coin with your smarthphone too

there are plenty of robbers out there and many already seen their phone robbed in some place around the world, and you're saying that is the best place to store your bitcoin fortune...

i prefer my desktop secure erased first and then a fresh clean so installing, the simple rule is to not install anything and do not browse on shady website, google will help you on this, you're done really nothing more is needed

This. Even if I was sure that online wallet is secure and never will be hacked there is always possibility of physical robbery, you can drop your phone, soft update can go wrong etc.
There is no such problems with stationary PC. Even I thief broke to my home (highly unlikely) he would take my laptop or smartphone first, because my PC is rather heavy and big.

I wouldn't say the opposite but the most important information here is that nothing is really safe if you don't know what you're doing. Android or apple phones may be safer than a windows PC in most instances but you could still download a dodgy app or get some virus from clicking a dodgy link. People could also lose their phones and if they haven't got a back up then they're screwed either way. My advice is to just know what you're doing and protect yourself and back up as much as possible in case something goes wrong.

How about you own two phones? One for bitcoin, that you keep at home, like a PC, and that you never take out ; and a second one that you use as a regular phone, and maybe for bitcoin change.
Doesn't sound too bad I'd say. You can get cheap smartphones for $50 nowadays if you don't want to put too much money in it.

Using desktop has much more risks, so many virusses, links, downloads, can cause a robbery.

lmao seems u arent familiar with smarthphones at all? You dont lose your coins if you drop your phone, you can revover it easily. btw your pc can just malfunction, get virusses, get damages and tons of other things aswell.

For a thief to access your coins, he would need to unlock your finger print to even access the phone if u have set it up, or your passcode or pattern code, then he has to unlock your app (if you have set up passcode for apps), then he has to send your money which also requires the passcode. Untill then i already have transferred my funds somewhere else, so good luck buddy.

There are two risks to this. You can have a less technically secure desktop but it is more likely to not be stolen or you can have a smartphone which is technically more secure but more likely to get stolen, lost, or broken. With a desktop, you can control everything and all the software installed on it. You can't do that with a smartphone. A desktop can also be configured to have encrypted hard drives, sandboxing, and whatever else that makes smartphones more technically secure. After all, a smartphone is really just a tiny computer. Desktops can also download the full blockchain so you aren't relying on someone else for the right data. A proper cold storage desktop wallet cannot download viruses and should not have anything on it except for the wallet software. Also, a desktop cannot be as easily stolen, lost, or broken as a cell phone is.

Really? How do you recover the coins from a phone you dropped that the screen completely shattered so that it is unusable? And smartphones can malfunction, get viruses, and become damaged and tons of other things as well.

That is only if you set a passcode for your phone, the app, and the wallet.

Strongly disagree with this statement. When thieves stole my phone I couldn't even use 2fa and sms verification but I was lucky to not use any mobile wallet. I might lost all my BTC. Bitcoin Core in a safe PC is the best choice for BTC storage. I don't feel safe when I have anything in my phone, even my photos. I regularly clean my phone and take backups to my PC.

They can be safer electronically but physical robbery is a great risk, also breaking the phone, or loose it.. I stick with computer wallets, if you know how to keep it safe it is still the best way of storing your coins

This is just plain wrong. Your private keys are just as much at risk on a smartphone as a laptop, perhaps more so depending on the phone. This is why using Mycelium with a Trezor on Android is so popular.

You can recover your coins from another device if your phone breaks, regarding stealing if you have money stored in your phone u must be smart enough to have passcodes on it aswell. Untill the thief has unlocked everything i already have transferred my funds somewhere else.

I surf the web, download movies, games, etc. on my pc so its a greater threat than my phone, not to mention i can access my funds on my mobile much more easily and make payments.

I also surf the web, downlod movies, games, etc on my phone as well. So my phone is just as big as a threat to my wallet as my pc is. Except I also keep my coins on in a cold storage wallet that isn't connected to the internet, cannot download anything, and only has my wallet on that. That is far more secure than storing the Bitcoin on my phone.

And if you think you can't get a virus on a smartphone because you downloaded the app from the official app store, think again. Just do a google search and you will find many cases of apps that were viruses that were allowed on official app stores.

If it wasn't created offline it's not safe.

I think iPhones are safer than desktop and Android less safe, majority of comments here are about Androids, with iOS you are pretty good secured. If u want to access to my phone u have to cut off my finger to even access my phone not to mention passcode for spending my btc, so until you have spend the time to even access my phone, i have transferred my funds somewhere else.

I think this is a reckless statement to make... Most people do not even run anti-virus software on their smartphones and they install any crap possible on there.. clicking through the

options, without even reading what they saw there. I bet you, if someone sneaked a option in there to allow anyone to read all their text messages and access their whole gallery and

listen in on their phone calls, they would not pick it up.... Just include it with some Cool App or cute game, and they will click through it like a hot knife through butter. People are quite

ignorant, when it comes down to the technical things.  ::)

First of all, fingerprint sensors are easily fooled. Secondly, they don't even need your fingerprint. They can just enter the backup password to access your phone. Same goes for androids. And getting the passcode for your wallet might be different, but it will be the same difficulty for both android and iphones. Even so, you could still end up downloading a virus to either type of phone since they are both vulnerable, and that could steal your Bitcoin too.

Exactly this. No matter how safe you coins on your Smartphone are if you just lose your smartphone. Same goes for laptops btw. That's why I prefer a trusted online wallet.

That is so much less secure than either of the two you just mentioned. The most secure is to use a hardware wallet. Having the wallet on a desktop is still very secure, much more so than on a phone and much much more so than an online wallet.

But you have to also have a pass/fingerprint - code on your phone, because if it is stolen or lost, the security wont matter. Other than that, it is true that there are less viruses for phones, especially iOS phones.

Of course a mobile wallet developers would say it's most secure on a phone. But I think that's totally wrong. It may be more convenient but by default it is not more secure - as others said it comes with a whole new layer of insecurity that is carrying it physically. Using best practices it could maybe be considered just as secure on phone or desktop but to assume best practices is wrong.

Yes, I guess you can say that. Today it is still more secure to store digital currency in your smartphone. But in a near future smartphones will be the main target of hacker attacks to steal all sort of of precious information. That day, not even 2FA will save you!

This is very misguided, first of all, WHAT smarthphone, android is far less secure than ios. Windows hoever, you'll know for sure that you lose your coins...

There is no such thing as a secure smartphone. You should never keep more bitcoin on your phone than you are prepared to lose. The only exception would be to use Mycelium on an Android phone that supports USB Host (not all do) and use a Trezor to sign transactions. That way your private keys never touch the phone. If your phone cannot work with Trezor just use the Trezor with your laptop and send bitcoin to your phone as needed for shopping.

This is nonsense. You have way more chances of losing your phone as in physically losing it because of a mistake, than getting your Bitcoin hacked on a desktop given that you are taking some really basic security measures. Just download anything strange and don't visit strange webpages and that's all.

If you visit any got websites and run unknown programs that there is no difference where to lose your money on your smartphone or laptop  ;D

Your phone is just like your wallet in your backpocket, so many people have a wallet with lots of cash, credit/debit cards in their wallet. Just because its easier for people to steal your wallet doesnt mean i have to suddenly leave my wallet at home and only buy things from home, thats doesnt make sense at all. Just like people taking their wallet with them they can do the same with their phone. Not to mention a phone is much more secured than a wallet. The future is mobile payments anyway.

alot of you are talking about data security of the apps and less ability to receive trojans on a iphone..

but putting the app/OS security to one side.. alot of you are forgetting one important thing..

most phone apps are just glorified browsers which contain no privkey or tx signing within the phone. as the privkeys are located on a server belonging to the app's creators..
and i think that not have sole control of the privkey is the main reason to only store 'pocket money amounts' on an address.

I don't agree with the sentence "Storing money on Smartphone is far more secure than desktop or laptop" just because 1 reason, let forgotten your smarthphone anywhere or stole it, is by far more easy than a laptop/desktop.

Is by far less secure?, no, but as i said is more easy stolen your money from smartphones.

This

Apple and android have zero-day exploits available to few people as well. Who knows what could be done with these exploits.

I agree with that. In fact, my old iphone 4 stopped charging some days ago. There I had two factor authentication for some accounts with bitcoin online. Fortunately, I got to change the authentication before the phone died. I would have likely lost access to the coins if I had not realized about the phone not charging.

Not very secure.

i feel more secure on linux os (installed only for bitcoin transactions), than any other smartphone os like ios or android.

Android is far from secure.
And iOS is secure only because it avoids you to installing unwanted apps, since anything outside App Store iOS says "no".

Lucky that you managed to spot the charging issue, although i'm sure you could of just repaired the charging module if need be. Also would there not be anything you can store as a backup for those online Bitcoin services and save it elsewhere?

So to put it short; you are safe from third party apps because you can't install them.. son't know if it's more funny or sad..
I would never store anything on my phone other than dust money, i don't think it has any notable security, and it can also be stolen, unlike desktop, which is far more unlikely.
Just run linux on a desktop and u will be 99% more safe than any windows machine, no need to set up mobile wallet on ur phone.

btw when ur phone gets stolen, there goes your 2FA as well..

You leave your fingerprints everywhere[1].

The overal idea that some device is more secure than another is nonsense. It all depends on what you want to defend against. If you do not define the attack you cant claim one is better than the other. E.g. a smartphone would usually not stand against a brute force attack, because hardly anyone[2] has a long pin. While its common or easy to have a lengthy 20+ symbol password on a laptop or desktop computer. A smartphone is more prone to shoulder surfing which is hardly an issue with a private desktop, but might be for a laptop used in public.

A desktop can be more vulnerable to viruses and malware, but this greatly depends on user behaviour. Keeping your system up to date and the same logic as with iOS applies. 0 days are expensive for all systems.


To add to this, rooting and jail breaking is common among many because they want to install different (stolen) software from possible unsecure sources. This is not a feature that keeps a system safe, its just a feature that keeps a system safe if the user does not go against it. In the end security is an user feature, not a system feature. Always, no matter which OS or device. Well unless you special purpose hardware.

So far I tested Xapo, Snapcard(BTC, LTC & Doge), Coinbase and breadwallet(cold storage) with IPhone. Most of time I use Xapo they have a nice app and good customer support.

I can't agree enough with your assessment Shorena! To compare two or more different systems is ludicrous in my opinion. It all depends on too many things.

Give a fool the most secure system and he will break it, lose it or whatever. Give a smart man any option, even the less optimal and he will do good by making right choices. Simple as that!

I've realized before that phones are pretty dang safe, the main part i like about phone wallets is that everything is just so much more convenient than paper wallets, if i need to check the balance on my address i can just open up an app and check sending and receiving money is also way more convenient.

 But the thing i don't like about the breadwallet is its UI, it only has 2 pages and not a lot of information

But your phone can more easily be stolen or lost.

If the attacker has physical access to your device, then his work will be easier, no matter how more secure your system is.

And you'll have to backup your keys somewhere else too, so it doesn't really matters

I have experience about web wallet and moblie wallet
oneday my ymail get hacked and i lose all of my BTC at blockchain, Bittrex and local exchanger

but my satosi at xapo still secure, basically xapo use 2fa
and 2fa only avaible at mobile aplication

now Im using xapo everyday it's more secure than blockchain or other web wallet

Im never use dekstop wallet like bitcoin core, electrum or etc.

Blockchain.info and I'm almost sure all exchanges accept 2FA, but don't force the user to use it(I don't know if Xapo does), so they are not less secure at least in this point.

I like blockchain because they don't really have your private keys, so in theory they can't steal your coins even if they really want

Im use 2fa called authy i install it on my phone and google chrome (https://chrome.google.com/webstore/detail/authy/gaedmjdfmmahhbjefcbgaolhhanlaolb)

my Mistake is i instal 2fa at my google chrome
and hacker aces my computer use RDP

this virus called "rat"

It's true. I use Android, and I feel like I've done my best to make it secure (up-to-date Cyanogenmod, no GApps/Play Store, Fennec Firefox only, VPN,  AF+ firewall etc), but I still feel like a smart guy using the crappy option  :D Still not picked up any malware (or lost coins) on my various phones.

I am waiting impatiently for a decent modular phone platform (Ara/Puzzlephone/Fairphone 2) with an OS that's actually designed to be secure (as opposed to one that might as well have been designed to be insecure)

I wear it during blockchain in android I have never encountered a security problem.
Bitcoin not worry we will be lost because we have to enter a pin when opening his application, but in my opinion both desktop and mobile has good security

Anyone who makes this ridiculous claim, whether android or iOS has obviously never looked into the dangers associated with baseband RTOS.

That's actually true tho, storing your Bitcoin on a phone is secure enough. But you also have to install an AntiVirus for your phone, and you should be wary to connect to a public WiFi.

I see my phone as a digital substitute for my normal wallet, and I will never carry around $ 1 000 000 in my normal wallet. Why would I want to carry that amount of money in a wallet anyway? A smart phone might have exploits not being revealed to the public and you could lose everything.

Loads of people have had a sim swap being done, by a company employees working with syndicates to get access to a persons mobile authentication, when they log onto their internet banking services. Why would they not do this with people, who use their phone as a digital Bitcoin wallet? 

There's a lot of thief out there waiting for the right moment to steal smart phones. That's going to be the worst thing that could happen if you are using smart phone with 2FA.

Being on you smartphone is more hazardous because of the use of unsecured wifi connections when you are out and about.

It can be as unsecure on your smart phone (iPhone is the worst since you can not configure most opinions on apple products) as it can be on your wifi at home if it is not setup properly behind a router with WP2 encryption. Always use a program that can mask your ip so it makes it harder to trace your location to keep people from hacking your connection to get your passphase.

I don't know about more secure, but it is sure more convenient since we almost constantly hold our phone which means we could check our wallet at will. But I must agree with Sir Carlton Banks, the use of VPN would helps. Though I rarely use VPN when accessing wallet from either laptop or phone, but i've read some tips on facebook group for bitcoin that the use of VPN would helps secure our transaction.

There is no risk with connecting on unsecured wifi when using Bitcoin clients.

Transactions are signed locally and broadcasted to the network using internet connection. Private keys are never sent to the network either. The attacker cannot modify the content even if the connection isn't encrypted. Modifying the transaction by changing the inputs or outputs would make it invalid and it is impossible to get the private key either.

It is possible for VPN provider to initiate a MITM attack which can capture your information nevertheless.

i have bad habits always forget when I put my smart phone and that is why i lost my smart phone several times
and after that incident i decide will save all my important document also my money in my laptop

^This is the only golden rule one needs to follow to keep their bitcoins safe. Put maximum of your holdings in a cold wallet, keep some on your desktop wallet for day to day activity and a little on your phone for when you're away from your desktop and keep several backups of all of your wallets and that's it.

Keeping bitcoins safe is easy, don't know why do people have to make this complicated.

I think storing on desktop or laptop is more secure rather storing in my smartphone.

First factor is, smartphone can be lost so easily. Also i usually forgot where my smartphone is.

But for laptop or desktop is always using at home.

Storing bitcoins onto a paper wallet or on a physical (DIY) crypto-coin (~ for the purpose of hoarding them) and keeping it at the most secret corner of your house is in fact the most safest way in my opinion.

But for the sake of daily transactions, storing bitcoins on smartphones would be the safest and easiest way. You can directly send required amount of coins by scanning the recipient's QR code only. Nowadays one can store Bitcoins and other altcoins only at a single wallet (thanks to Coinomi's multi-wallet app).

Although there's a risk of getting your phone stolen, but that would be your carelessness! That's why I always carry 2 phones and mostly use the $20 phone at public places (~ where there's more congestion and a chance of getting pick-pocketed) only for some important conversations and the $600 one remains inside the secret chamber of my bag.

As per as apps are concerned, I don't feel the need to root/jailbreak my phone in order to download malicious apps. I'm pretty much contented with the apps I get from play store/apple store. (I have a spare rooted phone only for doing all sorts of experiments though :P)

Again one might think about getting his phone robbed by some felon, first of all I would suggest them not to make any stranger feel like you are the richest guy in town! And not to meander around quite places for a long time, especially when you are alone.

Its got to be worth a bit just knowing people are hacking ur phone anyway

If you mean that you leave some bits in an open wallet to know if your pc or phone got hacked, then I understand it right. I also do the exact same thing. I have around 0.12 BTC in an open wallet to see if everything is still fine.

Both laptops/desktops and phones have their risks.

It depends on which one you're most comfertable with carrying around. I believe anything without internet is the safest way to store money on.

I'd only connect it to the internet if I either need to take some money out or put some money on it.

no he is saying that smarthphone are not immune from virus and stuff like that like dsktop, they are also more hard to intercept, and antivirus ar enot as strong as desktop version

personally i would store bitcoin in my phone on small quantity, just for spending purpose

It will still be OK if the wallet we use has online storage, we'll just need to reinstall it and they'll instantly recover our data, isn't it?

Would be a good idea to use an old smartphone for cold storage but to carry all your coinage with you would be foolish. I have lost many a phone especially when drunk leaving them in pubs dropping them on trains or falling into the toilet.

太棒了

But there are some risk, for example ; easy to get stolen or get broke if we are not take care of it
For me, I''m better put my password to my both device ( laptop & smartphone ) so I can having some backup if something bad happen

So,what you think more secure?android or ios?

IMO definitely use a 3rd party VPN app, and I also use AF+ to setup firewall rules that stop apps from using anything except the VPN. It's kind of annoying on Android now, you would have been able to just set some easy-ish iptables rules up before KitKat, but now the tables that are setup by default make it a real job to use iptables yourself.

agree with delek, i have experience lost my phone and contains my bitcoin.
I immediately opened my email to get in to my wallet and move private key and all the coins.
fortunately all my coins saved. no more storing bitcoin in mobile phone i feel desktop more safer.

Altough before i was nt knowing about these thing then also i use android wallet apps to store my btc.

Storing money on smartphone can't be a good decision as mobile can be easily lost or got stolen. But to use and pay even with bitcoin is much more easier scanning QR codes than from laptops.

Both of these ways of storage have their drawbacks and their strong points. Yes Android and IOS applications are sandboxed and this makes them safer. Also there are no so many viruses developed for these platforms.

I would still never store huge amounts of bitcoins on the phone. Just the point that I can lose it makes me very uneasy!

Definately make a back-up of your wallet and put a code for login. That way your stuff is always protected.

You also don't want your 2fa codes on the street right? Use a code to get in the phone.

Ok, then I was wrong in that. Well, I also store a small amount in my blockchain.info mobile wallet, but never more than what I would have in my physical wallet. In my case that is around $50 or so.

I heard about the Blackphone/Silent CIrcle when the first model came out, and I think they're still including Play Store/Play Services, which I can't justify when you can replace them both (and both are closed source, with alot of capabilities to use and assign app permissions, as well as vacuuming up loads of user data). It would be interesting to see if you could get a version of that OS without the Play stuff bundled with it, possibly source of SilentOS is available and it could be built from source.

Apart from that, Silent Circle is another good example of the field diversifying a bit more, and you've gotta hand the credit for that to Google really, as much as I don't like them. Hopefully this strength in depth will eventually make open platforms on mobile the best choice.

Phones are less secure given that most users will jailbreak it
One malicious app, or simply losing the phone can cause bigger issues it is also why services such as Blockchain.info and other wallets recommend not storing large amounts on phones simply because their is risk there.

For browsing unsecured websites, without ssl, you would need one. If not, Bitcoin transactions are fine, private keys aren't sent over wifi.

I'm pretty sure most wallets have HD features already, you only need to backup your seeds and you don't need to worry. I'm pretty sure you don't give out your phone randomly to your friends or them uninstalling anything.

I'm locked out of my wallet due to damn 2FA and can't run my faucets at the moment. Really annoying.

Secure, yes. Annoyed - very!

lol
faucets?
What did you lose, 10k satoshi?

Anything that's connected to the internet has a risk factor, whether if it's a phone or pc/laptop.

I would store it on something that doesn't have the internet connected to it.

iso to android you can make just as secure both are the same it just depends on how you store your coins what wallet your using and how much you are placing on your phone. I have my wallets on other devices besides my phone so I can access it on any and uses a pin and password to access or spend coins on my phone. If its lost I can send a signal to kill the phone and wipe all data on it if needed. So even if lose it I wont lose my coin or personal details and has wake up option if phone gets turned off. If another sim is placed in it will ask for pinto change so my phone is very secure. only way someone is going to access it is if flashing and wiping it, and even then wont work on network due to being blocked so can only use as like a notepad.

I would absolutely never store more than 50 bucks ish of btc on my phone- way to many ways to lose your phone and its already awful losing your phone let alone losing your btc.

A powerful desktop that could run a tweaked Armory wallet is probably the most secure system I could think of that could be relied to keeping large sums of bitcoin. Smartphones are just too delicate to be used as a orimary storage of big amounts of coins.

its just like you're using any hardware wallet, you can lose it anyway,but there must be way to recover it back

It's one of the most insecure storing methods. You lose your phone you lose your coins. Your phone is hacked your coins are stolen. Somebody take your phone from you he has access to your money. Never put BTC to your smartphone.

How about SmartPhone + Armory, it's the most secure combination.

I would have thought phones would have been a lot more insecure than a PC wallet... I think I agree with you.

I call bullshit on this one. Anybody with half a brain knows that phones are the most insecure electronic items that you can ever touch.

Not just that they ping the GPS coordinates to possible thieves (so possible armed robbers know exactly where the chest of gold is).

Then you got hardly any antivirus for phones that works, nor you can verify the signatures of those files you download.

Storing large amounts of BTC on a phone is like begging to be robbed.

Have to realize that that requires alot of storage space being used if you got with the smartphone option.

As a basic phone with no security yes. But having it locked down and a lot of stuff stripped out and security locked can prevent all of what yo say. Take the ping you can disable this on apps requesting access to it and limiting it. YOu only need anti virus on your phone if you are downloading a lot and even then most are useless. One am using seems to do the trick right now is CM security that shows any leaks or shit trying to access my stuff and never had any problems with it. I am also on a custom rom however this has been cracked down on security and a lot added and also removed from the default one that has vulnerability in it. Having a phone from a shop is not secure it is what you do after that to make it secure that counts.

https://bitcointalk.org/index.php?topic=1270063.0

I personally think that for pure beginners, insured web wallets are the best solution. I know many people don't like it as it's the equivalent of using Paypal but for some people who just want to buy and forget without the hassle of understanding how to backup and save your stash, it does not sound too bad to keep it on Coinbase or Circle, granted they have the 2FA enabled.

Despite that, you won't have full access of your keys and you have to comply with their terms. They do restrict certain transactions. Circle only covers up to $100 and it isn't perfect. Coinbase covers only if the hacking is due to their incompetence. A normal desktop wallet is secure enough provided that you have no virus which is easy to achieve. I have stored up to $200 on my computer and to this date, I haven't lost a single satoshi.

For me I just use my phone much closer to me

Even if we use our phone to store the bitcoin wallet it is necessary to have one or few backups because the phone is not static like PC and can be lost/stolen at any time.

I can understand the point that is being made. The system of iOS might be more secure than android but at the end of the day, a mobile phone is still an electronic device. There is a bound to be a zero-day or fault that not even the developers know and if there is incentive to find it, people will look for it. To this day forward, I will believe a paper wallet that is safely stored away from any harm (environmental, random acts of god, etc) is the best way to keep your bitcoin. I feel every electronic device has some flaw. The second best to a paper wallet would be maybe a Hardware wallet which would keep your coins secure.

For me i prefer to store it in laptop, phone can be lost and easier to broke compare to laptop

I love bread wallet on the iphone i have been using it for ages now, however im not sure i would wana keep all my bitcoin there.  i think paper wallets are still one of the best options out there......  ::)

i dont know which better between ios and android for store bitcoin or used bitcoin transaction,but if you said smartphone better and more secure than computer dekstop,i agree with that,but i have my own statment why smartphone is better,that because we always bring smartphone every where,and not bring dekstop PC everwhere ;D

I agree with the op. smartphone seem to be the safest way to store your bitcoins. I use  mycelium btc wallet. can check  balance evrywhre I go and a pass phrase option to  secure your bitcoins

It depends, i wouldnt store my bitcoin on my phone. i hold some there but its just for spending. If im holding then theres no other way to do it than a paper wallet.

I wouldn't store anything on my phone. It doesn't seem the safest option at all. Your phone is easy to get stolen as well.
I would put the bitcoins I don't use on a cold wallet.

As long as you protected your account with 2fa and use unique password your coins are safe. Never ever use "remember password". Not a good idea.

yah, you have point there, but its very technical to some people that  wouldn't understand the technology of bitcoin. this is the best I can explain to them. mobile wallet+bitcoins

If the android device is rooted, it will not be secure to install bitcoin wallet on it
To be safe while using mobile wallets, I export the private keys because the mobile might get broken or stolen

My device is rooted and ive had no problems yet. thats not to say i wont get any and i dont think stagefreight has been patched much yet either which puts almost 99 percent of androids at risk. For mycelium i have the seed written down so if i lose my phone i can at least recover my btc. Ive already lost 0.4+ btc from trying to teach my phone to swim.

Having money on your phone is always handy, since you bring your phone anywhere you go, you can just pay with bitcoins on your phone. I wouldn't hold too much on your phone since your phone could easily be stolen, if you've made backups of your keys, you should be okay though. You wouldn't have anything to worry about if you go that set up.

Storing money on smartphone or desktop or laptop, we have to think about the security of all these three. Desktop or laptop or smartphone every where we have to use internet. and virus and scammers comes through internet only. So better to do some precuatious measures and make it all secure with some kind of trusted software and pass keys.

Never forget that you phone is small and thus can be broken, stolen and lost far more easily than your desktop computer. I'd say that you can store up to 1000$ of Bitcoin in your phone, even if personnaly I'd stop at 100$.

What are we really talking about here? about Bitcoin? or real money? For me, all have the same amount of safety and risks. Bitcoin wallets for smartphone is just a support feature by the walletproviders to easily access your wallet through your smartphone. You can access your wallet through both computer and smartphone, and it all shows the same thing.

I agree that iOS is more secure, it has a closed nature and I imagine installing something malicious is very difficult, Using wifi or public networks while dealing with BTC in a phone would be a bad idea IMO though.
