Hey! Thanks.
What do you think @mocacinno qualifies to be a perfect privacy centric wallet as per my understanding only Bitcoin's transaction can be consider as non private as you can find out from which wallet it originated and which wallet it got credited.

I personally use wasabi as a hotwallet... From wasabi I either coinjoin or use chipmixer, then my funds go to my hardware wallet.

Wasabi is great, it has a visual way of showing me which funds have been coinjoined and which are still linkable to my identity... It also has good coin controll features and works over the internally started tor router... To bad the coinjoin feature doesn't work when you use wasabi in combination with your hardware wallet... That would have been an ideal situation.

As per my understanding and knowledge that I have acquired from Google there are two wallets that are Privacy centric  and they are:

  • Wasabi Wallet
  • Mycelium Wallet

At the moment these two wallets are known to store Bitcoin. Wasabi is only available for desktop devices and Mycelium is only available for mobile devices.
As Mycelium allows you to use TOR network for transactions I am considering it to be Privacy centric.

Now, the question to all my fellow members is, do you know any other cryptocurrency wallet that provide the same kind of feature or as per is Privacy centric. I am looking for wallets that support not only Bitcoin but other cryptocurrency too.

Thanks.

 
 

If the ability to connect using tor classifies a wallet as privacy-centric according to your defenition, you should add electrum to your list since it supports connections over the tor router out of the box (click on the green button in the bottom right corner, go to the proxy tab). A lot of other wallets (like core) can also connect trough other nodes over the tor router.

You can use any provider like Bitpay.

Bitpay isn't well-liked in this community...

You can read the reasons in sites like this one: https://debitpay.directory/anti-bitcoin/ (not my site)

Instead of bitpay, why not use btcpayserver, or run a core or electrum daemon and use the json-rpc interface directly

but are think when i open on other wallets with seed will get all balance or may any issue occurs

You can import the same seed in as many wallets as you want... Your wallet in itself does not contain any bitcoin(s) anyways, it only contains the master private key from which other private keys can be derived (and maybe some metadata like labels). Derived keys can be used to sign transactions spending your funds.

For example, if you have a wallet managing 1 private key, and the address belonging to this private key has one unspent output with a value of 1 BTC, you can import the seed for this wallet into 50 other wallets. Each wallet will show a spendable balance of 1 BTC.
If you spend this unspent output of 1 BTC in any of those 51 wallets, the balance of each wallet created by importing the same seed will be 0.

Offcourse, issues can occur if you mess up the exporting or importing of your seed.... Or if the wallet you use to import the seed also has technical issues.

--snip--

are they will take more money? or fee for this ?

No.

If you export your seed and import it into a decent wallet, the decent wallet will be able to spend the funds of your blockchain wallet directly. No extra fee for importing your seed...
You'll need to pay a tx fee when you create a transaction tough, this is independant of the wallet you use, but the process of exporting your seed from blockchain and importing it into a decent wallet is purely technical, it only costs your time.



By the way: exporting your seed from blockchain and importing it into a decent wallet decreases your security. You now have an online wallet that's saved on blockchain's servers (encrypted, but still), you potentially have the seed on other media, and you have a desktop wallet using the same seed... It's a good idear to empty this wallet completely by creating a new desktop wallet in a safe way and moving all your funds from your blockchain wallet to your decent wallet as soon as it's convenient to you.

All this being said, don't hold 7+BTC in a blockchain wallet... Really... A trezor costs ~0.008 BTC and is a lot safer than any online wallet.
A decent desktop wallet is safer than your blockchain wallet, but defenately not as safe as a hardware wallet.

nc50lc is probably right, an other option might be the conversion rate.

If you bought the BTC at a time when the conversion rate to USD or EUR was higher than it is right now, it might look like 20% of your funds are "gone" when you look at the FIAT equivalent.

1 BTC today is the equivalent of ~$9100 at this point in time. It's possible that in a couple weeks, your 1 BTC is worth only ~7300, so it looks like 20% of your funds "dissapeared". But in reality you still own 1 BTC, it's value just fluctated.

If changelly showed you 12ANFPJeKwciJMWgSUgSmfKW5SSqxyrU1a or 3CGFZhgpTpGSDuk2x61iqESXeD1945TMMc as a deposit address, they should have received your funds...

Well, i've learned something new today anyways... People do get scammed with tBTC.

This being said, it does seem like the amount of cases is still very small, and rightfully so, those people getting scammed seem to have no clue they're actually transferring wealth. I guess some people are always susceptible to scams, no matter how transparent they are.

It's like buying play money and trying to use it in a shop and being successful in convincing the shopkeeper the stamp "not legal tender" actually means "real money". Seems completely unlikely to happen in the fiat world, but for some reason some people seem to drop several iq points as soon as any digital form of money comes into play.

I'm having a bit of an ethical problem tough: i do think tBTC is usefull, and i'm 100% sure some people will actually need it for legit reasons. Some of these reasons might be private (for example: somebody building a mixer), and i believe in an individual's right not telling me why they need the tBTC.
On the other hand, they might be sketchy and use the tBTC for illegal activity's....

  • Do i tell new people i no longer lend out tBTC.
  • Do i start doing "backgroundchecks" that cost a lot of time and effort, especially for a free service.
  • Do i keep lending out tBTC, eventough part of it might be used to scam... But then again, allmost everything you lend to anybody can be used to scam in one way or another...
I haven't got a clue... Does the good outweigh the bad, is it worth my effort,...  Sad


10  Bitcoin / Bitcoin Discussion / Re: Cryptocurrency mixing services do more harm than good to blockchain technology on: July 09, 2020, 12:39:04 PM
Well, it's all pretty simple... Bitcoin is a system to transfer wealth. Just like cash or gold.

When i was young, you could buy all kind of illegal drugs at the gate of our school using fiat, mind you, this was many, many, many years before satoshi published anything even remotely related to bitcoin. Still, my mother forced me to go to school and she gave me pocket money every month (which I used to buy weed).

It was known that if you wanted to avoid taxes, your had to bring your "black market money" (money you made by doing jobs for which you didn't pay any taxes) to luxembourg. They accepted your cash without questions, gave you a high interest rate and they didn't communicate with other governements for tax fraud purposes. Still, most transfers were completely legal.

It was known that certain shops in certain city's took in stolen money and "black market money" and laundered it. Still, an average person like me could visit these shops and buy a newspaper (or whatever they sold)

There were jewelers that took in stolen gold, melted it down and poured it into legal-looking forms. Still, an average person like me could walk into these shops and buy a wedding ring for his wife.

That's just the way any system to transfer wealth works. It's mostly used for good, but it can also be used for bad. No need to ban all banks, all shops and all jewelers. No need to close the schools or burn all fiat money. Just find the drug dealers, money launders and other criminals and punish them accordingly.

Mixers serve a very good purpose... They protect not only my privacy, but also my family's well-being. I depend on services that take crypto currency that can be linked to me and in exchange give me a slightly smaller amount that cannot be traced back to me.
I know many, many other completely legit people that do not posses a single satoshi in their private wallets that hasn't been mixed or coinjoined.

I do agree that if you ever found a system to transfer wealth that could never be used for any illicit activity, it would have a better image than any "other" system to transfer wealth (like fiat, gold or bitcoin). But i don't see this happening anytime soon.

It's not because a service gets used by scammers that it does more harm than good...

I use mixing services all the time to protect my family and myself against a $5 wrench attack...
12  Bitcoin / Bitcoin Discussion / Re: What's up with the need for tBTC? on: July 09, 2020, 08:35:28 AM
--snip--
have you asked them why they want such large amounts for?

I tried... Didn't get a clear answer tough...

I haven't heared about anybody getting scammed with tBTC (yet). Seems like a strange attack method. I mean, you have to persuade somebody to either run a wallet that's clearly marked as a testnet wallet, or you have to convince them to start the wallet with a parameter that clearly says "testnet" or you have to convice them to run a "fake" wallet... Next to this, you'd have to convice your victim that he/she cannot use a normal block explorer. And you have to convice them that testnet is just like main net, and he has to ignore the "test" in front of everything, and the warnings everywhere, and the posts on forums, blogs,... that indicate that tBTC has zero value.

It just feels like a criminal would take the path of least resistance... Why scam somebody with tBTC? If you have to get them to run an "alternative" wallet, or a standard wallet in an "alternative" way, why not just push a completely fake wallet on them, one that's basically just showing fake transactions that get pulled from a central server? Or use some crapcoin or token and sell it as BTC.

I'm not saying it's impossible, since you guys have actually heared from such attacks i'm not doubting these kind of things do happen... It just seems unlikely to have caused such an "explosion" in tBTC demand
13  Bitcoin / Bitcoin Discussion / Re: What's up with the need for tBTC? on: July 09, 2020, 07:05:55 AM
The demand for tBTC is increasing since a few months ago iirc.

It is possible that those guys are confusing it with another token such as https://docs.keep.network/tbtc/.

Possible... However, what i forgot to mention in my OP is that the 18 requests were not only from newbies, but also from people that've been here for years, even somebody from DT2, and somebody with green trust... Same on twitter: not only new profiles, but also somebody with a longtime profile.
Seems strange to me that these people would mess up a worthless craptoken en a 0-value testnet coin.
14  Bitcoin / Bitcoin Discussion / What's up with the need for tBTC? on: July 09, 2020, 06:00:46 AM
I run a tBTC (testnet Bitcoin) faucet, and i've publicly stated i would loan out tBTC to anybody who needs it in the past... Usually i get 2-3 messages per month requesting "random" amount of tBTC from newbies...

After I explain the collateral I estimated a couple months ago will no longer suffice because the difficulty on the testnet rose from 10M to >16M, the block reward went from <0.4 to <0.2 tBTC/block and the price per Th on miningrigrentals rose aswell since my posts about loaning out tBTC, they drop the subject never to be heared off again.

However, yesterday i received 16!!! messages asking for loads of tBTC (most of them in the ~100 tBTC range). The messages were evenly spread between bitcointalk PM's, my 2 public email addresses and my twitter inbox.

This night, 2 more messages, resulting in 18 requests in little over 24 hours...

I'm missing something here... Anybody knows some secret I don't?

I mean, electrum has released version 4... I could understand people asking for tBTC to test out the LN on testnet... But you wouldn't need 100 tBTC for this. Other than that, i'm drawing blanks...

Those wallet download full nodes that's why it takes a long time to synchronize. I know, it will be good if your computer have good power to run those wallets. If your computer got some issues you could try Armory or Electrum.

The last time i ran armory, i did require you to run a full node underneath Armory... I doubt the structure of this wallet has changed that much.

Electrum on the other hand is indeed an SPV wallet, so it is indeed a lot less resource-hungry.

I like bitcoin core too, it is a full client wallet, but not good for beginners as it needs more money space and subsequent backup of each addresses used to receive bitcoin [...]

You only need to backup your file once. Core uses HD wallets.

--snip--

Maybe add a little sidenote: core didn't always use HD wallets, and you can still create a non-HD wallet aswell.
It would probably be better to claim that recent versions of core use HD wallets as a default.

(just nitpicking here... I agree with the general idear of everything you said... but i wouldn't want somebody with a really old, non-hd, wallet to think they didn't have to make backups)
18  Bitcoin / Bitcoin Discussion / Re: Transaction fees on: July 08, 2020, 10:43:19 AM
Nowadays almost all companies is money-oriented, and normal things exchanges or wallets apply transaction fees. That is for to cover operational
costs, exchanges or wallets that provide free transaction fees will definitely not last long. For me, no problem transaction fees apply, but don't be
too expensive. Therefore I always look for exchanges with the lowest transaction fees.

I don't know any decent wallet that charges a fee for the developers of said wallet (multibit used to do this years ago, but they stopped charging a fee after a while, and they even stopped developing their wallet). Wallets do calculate the tx fee, which goes to the miners (not the wallet dev's).

Wallets that still offer "free" transactions are making money off of you another way... Either by scamming you, or by upselling other stuff, by spamming you, by charging other fees,... Some centralised wallets do offer "free" transactions between users of the same service. They can do this simply because their users have no control over the private keys (all funds are stored in the wallets hotwallet), their wallet balances are merely a record in the service's relational database so sending funds from a to b is just updating a record in their db (and not creating and broadcasting a transaction).
I wouldn't use any wallet that offers free transactions... Not your keys, not your funds...
19  Bitcoin / Bitcoin Discussion / Re: Transaction fees on: July 08, 2020, 09:53:11 AM
Transaction fees is just like a tradition in crypto, in every transaction made there must be a fee applied, but some exchanges charge so high and this discourages some members in working with such exchange, for me I always go for exchanges with less transaction fees.

It's not a tradition... There are 2 kinds of fees that keep getting mixed up by newbies, but neither of these 2 types of fees are "a tradition".

Miner fees
These fees are actually described right into the bitcoin protocol. Every node, every wallet has this concept right in it's sourcecode.
A miner fee comes into play when you create a new on-chain transaction. It's the difference between the sum of the value of all unspent outputs used as an input and the sum of the value of all new unspent outputs that get generated by the new transaction. When miners try to solve a block, they can add the sum of these differences for all transactions into the block they're solving to the coinbase reward of said block. So, the higher the fee (in sat/vbyte) you pay, the bigger the incentive for a miner to add your transaction to the block he/she is trying to solve.
In the far future, the coinbase reward might consist mostly out of fees, if nobody would add any fees to their transactions, miners would have no income, so they'd stop mining => no new blocks => bitcoin would be dead(or the protocol would need to change)...
So, this kind of fee is defenately not a tradition, but a necessity.

Exchange/service fees
Many companies charge fees for depositing, exchanging, withdrawing,... These fees are part of the income model for the exchange. Exchanges are businesses, they need to make a profit or they'd stop existing. So this kind of fee is also not a tradition... I'm not arguing all fee models used by services are fair, but if you think their fee policy is unfair: don't use them.

There is a thirth kind of fee that has recently come into existence: a lightning routing fee... But this is new and most new members won't run into this kind of fee... Hint: it has something to do with lightning nodes that charge a small fee for routing lightning transactions.

Oh, whoops my bad lol, the faucet is using Bitcoin v0.15.2 which didn't have bech32 addresses! I'll upgrade the daemon to 0.20.0 today, sorry about that!

It wasn't really an error, but it does make your faucet look like it was made in pre-segwit times Wink
Let me know if you want me to try it out with a bech32 address!
