If he doesn't want to buy a hardware wallet, why not simply use Ian Coleman's code for start? https://github.com/iancoleman/bip39

Use it safely offline, get a 24 words seed and generate address(es) for Ethereum (default is Bitcoin, but there's a combo box there with plenty of coins) and here you are.
Of course, the seed will have to be saved safely offline. And all the traces also deleted. Only the addresses should stay "at hand".

OP can see the funds online on block explorers.
Of course, he cannot spend, but his wish was to be offline. This is great for HODL (although I don't really recommend HODLing tokens because they tend to go to 0 within months or days).

Bitcoin, din punctul meu de vedere, sunt bani. Cumparand bunuri cu bani ... e evaziune? Cand cumperi cu cash faci evaziune? Nu cumva depinde de vanzator sa faca bon, cum crede el de cuviinta?

Let's say you find somebody interested.
I don't think that anybody would look at an used Nano X if it's more expensive than a new Nano S, which does the same job at much lower price.
That means you'll have to sell at under 46 EUR (Leger sells now at 20% discount) and you'll have to find somebody that cares more about not spending than about having his coins as safe as possible.
I find that highly unlikely and the endeavor may not worth your time.


PS. The story is interesting, but it's wrong, higher electricity price may make some miners leave, but certainly not all and the difficulty will adjust, making mining profitable for them again.

Sa inteleg ca aveai asteptari?! Nu e cazul, nici macar "la case mai mari".


Si asta ar trebui de fapt sa ne bucure. Bitcoin e deja suficient de matur si cine are suficienti neuroni a inteles ca poate fi folosit foarte usor si normal ca mijloc de plata. Direct, fara intermediari, si deci fara KYC inutil.

Generate a completely new wallet.
Make sure you don't keep the private keys info online (mail, cloud/dropbox, your computer, your phone), especially unprotected.
If you plan to go for bigger amounts of money, you may consider buying/using a hardware wallet.

It's real (see discussion on btalk) and it's a follow up of the story where Peter Schiff publishes his son's Bitcoin wallet.

Very well pointed out.
Each of the 2 parts' declarations are clearly biased, but if something like ^^ that will happen then yes, the tool is good.
However, I also have my doubts, I think that they use Monero name only as advertising / to increase the awareness about their tool.

Yes they will; and will also get everything else you have in your blockchain wallet.
That's because most probably if you log in via their button you'll (also) send them your credentials, so they'll access freely your account.


Blockchain.com / .info has a long history of having its users targeted by phishing e-mails. I've got at some point 1-2 such e-mails while I didn't even had blockchain account 

21BTC is quite a nice amount. I would build a cold storage from those private keys. Keep in mind that cold storage machine, after the point the private key(s) inserted, will have to NEVER ever go online.
Since the addresses are also available, he can set up watch only wallet(s) which will be used to see the funds, create transactions (that can be signed with the cold storage), broadcast transactions.

And of course, the smaller funds he wants to sell now and then can stay on newer (bech32) address(es), maybe tied to a hardware wallet.

I would not move funds from the original place if not necessary; as long as the private keys are safely stored offline, as long as the transactions are signed with an offline cold storage, the funds of "a guy inherits 21 BTC" should be safe.

The year is not over yet. Keep in mind that even in 2017 the first 2 weeks of September looked bad. Who knew what was going to happen?
So why you rush it? The year is not over yet.

So this guy is bashing Bitcoin every time he can, still people send money to his son's address.
Since Bitcoin has big price variations, this guy has plenty of opportunities to say that bitcoin is bad (of course, he can conveniently shut up when Bitcoin is doing good).

Also with all the attention his twitter account gets will make his ideas reach even more users.

Is it me or his "son's Bitcoin wallet" story was premeditated as a win-win situation for this guy?

You know that ownership has to be proven, right?
If you don't have account info or even better the private keys, I'm not sure who can help you.

About blockchain.com, if you have been using their services for those wallets, you can try their support (although imho your chances are nearly 0). And this would mean that you can prove you had an account there and they will provide you your private keys or a working account.

"Anyone from bitcoin" clearly cannot help you. That's is not a private company and the only way to access those funds is if you have the private keys.

Thanks and congrats! 

Normal ca sunt, e o sursa de bani.
ATM-urile nu o sa dispara, doar ca sumele cu care se va opera fara KYC vor deveni extrem de mici, iar pentru restul .. declaratie de venit si toata "bucuria"...

You are far from a serious investor. You were hoping for some quick bucks.
A serious investor doesn't invest all in one step, he knows that investing smaller amounts over longer period of time minimizes the chances to "get burned" (at least for short period).
A serious investor knows that every investment is risky and crypto is even riskier.
A serious investor knows that Bitcoin price fluctuates a lot.
A serious investor knows that altcoins are even riskier than Bitcoin.
A serious investor will not try to somehow try to make the community responsible for his actions.

I would also add that even if you have the keys, if you are not keeping them safely (hence it's not only you who get access to the keys), you'll also lose the coins.
This means that the keys or seed should not be kept online (mail, cloud) and should also not stay on a computer that goes online. I advise paper and/or hardware wallet, with the mention that big amounts of Bitcoin should not "stay" on the hardware wallet you use daily, instead they should be tied to a cold storage.

"Up and down and up and down."
Zoom out, look at the big picture and stop panicking for nothing.
Or, if this roller coaster is not your game, just sell and forget about Bitcoin.

Ignorance, bad advices like this one, the overall advertising about hardware wallets which makes people think they are fool proof, all did its part.

For big amounts of coins (where "big amount" may depend from person to person) there's only one good solution imho: cold storage (and also this, only if properly used, obviously).

Possibly. Still, keep in mind that such companies may have their own (owned) buildings for office spaces or they are rented based on very long time based contracts. Also those office spaces may be customized.
All in all I expect that quite a lot of them didn't give up on those contracts yet and may not do that too soon either.
So your logic, while not incorrect, is applicable only after some more years like this.

You are most probably correct.
I was expecting I may miss some "orders of magnitude", but I thought that should be not a big problem since the goal was easier understanding, not being 100% correct.
However, the idea of adding the "four times consecutively" is very good and although I don't expect too many who didn't understand the initial explanation gasp the difference, I'll add that. Thank you.
