If you add the address it will be a watch only.
If you add the private keys, like omegascream said, you will be able to spend those coins.

Public addresses are used to receive, and private keys are used to spend.
Never share your privatekeys to anyone.

I don't understand what is the op so worried about.
If you lose your device and for some reason a hacker finds it, he will not be able to steal your funds, unless if it is a zero day exploit (which nobody knows any for now).
If someone try your pin 3 times  device will reset.

The maximum security for now for your bitcoins is a ledger nano or a trezor.

What kind of features could that be? I never thought about this, and certainly this can be an interesting perspective. However, I can't think of anything other than more coins support, which doesn't interests me.

Maybe some better integration with some crazy smartcontract in ethereum in the future.. However for now my nano integrates perfectly with metamask, electrum, mycrypto, mew, TRON, etc etc...

In ledgerI miss an integration with Steem. But that~s ok, i can live with it lol

Congratulations.
It is a hard work to rbak up an account here.
You had a fast grow recently, and it is not easy.



Somehow my life changed as well. I spend so much time here. I discovered that this place is somewhere I can ask anything that many knowledge people will quickly answer. Certainly one of the best places in the internet:)

exatanente. satoshi nao fez nada sozinho.
isso o theymos explicou uns mesrs atras num post brilhante, Satoshi's lesson.
https://bitcointalk.org/index.php?topic=5092492.0

Satoshi utilizou várias ideias que já circulavam na época da criação do btc. Ele as juntou e fez algo incrível.
Um trabalho de monstruosa dedicação, e feito gratuitamente, apenas ideologia.

What is suggesting makes absolutely no sense.

No one should have to give any authorization to receive money, only to send. This is how it always worked out in Fiat currency as well

If the user is careless and sends money to any address without verifying, it is solely his fault and he loses the money . There is nothing no one can do.

What you are suggesting, authorization to receive money, causes so many problems that it is not worth mentioning.
How would donations work? There would be so much more congestion cause there will be those transactions going back and forth...

Bad idea.

If you can't store a paper or this steel in a place where no one will find, then this will not give you any security.

Ofc steel is better than paper, however a paper can easily last 20 years, as I have seen already

If it is related to the bitcoinforum you can post in meta board.
There is too much spam in Bitcoin discussion board. I would try some other board, according to the art.

Maybe you are confused about passphrase and seed definitions.
Seed is the 12/24 words you save
 The passphrase is an additional"password" that will encrypt your wallet.

If you don't know the passphrase there is no way to recover. Myabe you can try to brute Force if you are sure it is similar to the one you think it is.

Passphrase is case sensitive, this means that Passphrase and passphrase are different.

This is slightly safer than a paper...
But if you make some different back ups of your paper wallet, there is no need to have this

It is beautiful and interesting, but not worth 40 bucks imo

People are willing to sell a lot of their data and posts useless stuff compromising even their reputation for a promise of receiving a few satoshis, probably less than 0.01 usd

Cryptocurrency is making bounty hunters crazy. It's better to become a beggar. You can easily get 5-10 usd by begging around your neighborhood, without giving any data

I agree with ETFbitcoin


None of those exchanges mentioned are decentralized, but etherdelta and other Dex based on ethereum smartcontracts. Unfortunately you can only trade ether and tokens there.

Until we have a truly atomic swap going on there will be no Dex between two different blockchains.

I like coindesk, blockgeeks, techcrunch, wired, Gizmob, theverge.

All of those have good and bad articles, justook for good ones

Personally I just delete any email sent from an unknown sender.

Just delete them and never click links in emails. If you want to go to the site in a email link, look first at Google and try to reach the official website, not the email link to it

Certainly that's the best time, and black Friday as well.

However, if someone holds a significant amount in crypto, I wouldn't wait a few months or weeks (risking my coins) to save 20 bucks.

Neither will bch, which is Roger Ver's blockchain.
The only truly Decentralized blockchain for now is Bitcoin. Bch is just a quick rich scheme.

I think it depends on exchange policy. Also, there is no guarantee that this specific address is yours and yours alone .
An exchange may decide just to use an old address to you, which belonged to some other account before , or even some other transaction from cold -hot storage.

If you think Bitcoin is about trading, certainly you don't even know what it is

Search in Google "what's bitcoin" and come back in a few weeks so we can discuss

Move this topic to service announcement (click the button on the bottom left corner)
Otherwise some moderator will soon delete your topic.

This board is for technical discussion, not for advertising

I am not enterily sure about this
Maybe if the transaction is considered small value according to their internal policy, your funds may remain in that same address you transferred for a long time.

I never used coinbase, but I know certain exchanges do not generate new addresses for new transactions. So if someone discovers a transaction you made, they could watch how much you sent there.

Additionally, you should ways create new addresses before withdrawing funds, to preserve your privacy. (Someone who knows one address of yours will not be sure about this second one, and it could be someone else's.
