Economy / Web Wallets / Re: Online Wallets

So the hardware dongle will work with their mobile app? If the mobile application is managing the keys, what is the difference between the online wallet and the mobile app wallet? I might as well just use the online wallet as they worry about securing my keys. I thought the whole point of having the hardware wallet is to eliminate your keys being stored/accessed anywhere else but that particular hardware. If that application has access to my keys via that hardware, then it is no good?

Can you plug them into your phone just like you can to your computer? You can if you have a dongle for phones but the hardware wallet should have an app for smartphones so there's no need to plug it on a phone. It also depends on which hardware wallet you'll choose as there are different types like some have buttons and screens. I do have a phone which supports USB Host mode. Do you guys know and use similar hardware wallets that you recommend? I would like to have a look and find out. Thanks so much.

Can you plug them into your phone just like you can to your computer? Your phone needs to support "USB Host" mode and you'll need to have a USB OTG ("On-The-Go") cable to connect to the micro-USB port on your phone. Most modern (mid-range+) smartphones should support OTG... but some of the cheaper, low end models may not (ie. Samsung Galaxy J1 does NOT). If you google "SmartPhoneModel OTG" you should be able to find out if it supports OTG or not.

Quote from: lenoli on July 03, 2017, 09:42:09 AM for trading online wallets are good, but for keeping high amount of btc is too risky, because they arenot as safe as desktop wallets, so while choosing online wallets, be carefully. for small amounts, i am using coinbase and its perfect for me good luck... Isn't the desktop wallet is pretty much similar to hardware wallet? Both "hardware" can fail. What happens if your desktop wallet fails?

Services like coinjar which keep your private keys. When you trade bitcoins, I assume you will need these services. Should you then transfer the coins to your offline wallet? I had never heared about coinjar, but after looking them up, it looks like they act both as an exchange and an online wallet. Offcourse, if you want to exchange FIAT to BTC, you'll have to accept that you'll need an account on an exchange somewhere... But my recommandation would be to withdraw your BTC to either a desktop wallet (for reasonably small amounts) or a hardware wallet/paper wallet/airgapped pc as soon as possible. A rule of thumb: if you're not the (only) one in controll of your private keys, you're not the (only) one in controll of your funds. Thank you. I will look in to those options.

Bitcoin / Development & Technical Discussion / Blockchain to protect information

on: June 27, 2017, 12:23:23 PM

I was just wondering how I can utilise blockchain to protect user data and integrity of that data. I want to store information on a USB memory(offline storage). How can I use blockchain to check the offline storage data? Since the blocks need to be connected peer2peer, I assume block chain is not really useful if the data is offline and nodes cannot communicate with other nodes?

Sorry but the second sentence didn't make sense to me. And why do you think I don't invest in bitcoin? Any good reasons? I am pretty sure there were people back in 2011 said not to invest in it but the one who did it are now wealthy.

Is it wise to invest now? How much do you guys think BTC will rise? Also looking way back at the thread in 2011,2012, their predictions were pretty much correct. Don't invest in bitcoin. Convert from your old currency to bitcoins. 250K per coin. I wouldn't mind that Quote from: keithers on June 21, 2017, 05:42:53 AM This thread has made it through many price milestones from the single digits all the way up to $3,000+ this year. I remember a few years back I think it was Stunna from primedice who was going to wager that a certain amount of BTC would be worth more than Berkshire Hathaway Class A shares. I think this is the year it actually would have passed that price
