I’m a 17 year old developer who’s been in the cryptocurrency field for a while now.

I wanted to ask you guys about different ways of purchasing crypto under 18.

All exchanges just as Coinbase, Kraken, etc. require you to be 18 and provide proof of identity to confirm this.

I have my own bank account under my name with access to Zelle. What I’ve been doing so far is using P2P sites like LocalCoinSwap and paying with Zelle to buy crypto off other people.

This method is extremely inefficient as many sellers on LocalCoinSwap ask for ID too and I really don’t want to send any documents to a complete stranger. The sellers that don’t ask for ID, add an insane premium like 15% or 20% on their prices.

Buying crypto just to instantly lose 20% of my money is not worth it in any way.

Do you guys have any other methods of buying crypto being under 18 where I won’t have to pay insane premiums?

Hey guys,

I don’t know why but I just remembered that I bought BTC in late 2014. I was out drinking with friends and we talked about something clompletely different, it just hit me. Now the problem, which probably isn’t that rare:

I created the wallet on blockchain.info and I know that I saved the keyphrase on an old phone which’s screen is probably smashed but still at home. But I have no idea what my wallet ID is.

The only thing I have left is login links (blockchain.info/wallet/long array of numbers and letters) to blockchain.info, which i used to create the wallet and buy BTC. But the website is down/leads to blockchain.com and the login link does nothing here, nor does my email seem to be registered anymore, since I don’t get a reset password mail.

I’m not into crypto at all but is there any chance that the coins are still there and I can find out my wallet ID somehow? I don’t know how many BTC would be in there, it’s probably not even a whole coin. But before I look through all my old devices I would like to know if it’s worth it.

Thanks in advance!

Some of you might remember my post from about a month ago where I shared a children's book I made that contains all 2,048 BIP39 words — the idea being that you can use the Book Cipher method to encode your seed phrase as page-line-word references and store those numbers separately from the book. The post blew up way more than I expected (400+ upvotes), and I got a ton of valuable feedback.

The most upvoted criticism: "This is just security through obscurity." Almost 400 upvotes on that comment alone. Other common concerns: "Now everyone knows the book", "A children's book is weird if you don't have kids", and "Amazon knows who bought it."

I took all of that seriously. Here's what I did about it.

What changed

1. A second book — for adults this time.

Several people pointed out that a children's book is a hard sell if you don't have kids sitting on your shelf. Fair point. So I created "777 Wisdoms for Every Day" — a collection of 777 numbered wisdoms that also contains all 2,048 BIP39 words. It looks like any other inspirational book. On your nightstand, in your luggage, on your office shelf — nobody thinks twice about a wisdom book.

2. A new encoding option that didn't exist before.

Because every wisdom in the book is numbered (#1 through #777), you now have an alternative to classic page-line-word encoding. You can use wisdom-number + word-position instead. Or mix and match. Or invent your own scheme. The point is: even if someone knows the concept AND knows the book, they still don't know how you encoded your references. That directly addresses the "security through obscurity" criticism — there are now too many variables for a simple lookup.

3. The "everyone knows the book" problem got smaller, not bigger.

Counter-intuitively, having multiple books actually helps. There are now two completely different books designed for this (a children's story and a wisdom book), with multiple encoding methods each. An attacker would need to know: which book you used, which encoding scheme, and have physical access to your number sequence. That's a lot of unknowns.

What hasn't changed

• It's still an additional layer, not a replacement. Your metal plate / paper backup stays in place. The book cipher is a complementary copy with built-in obfuscation.
• Two-factor by design. Book alone = useless. Numbers alone = useless. You need both, stored in different locations.
• The travel use case. A wisdom book in your luggage raises zero suspicion at borders. The codes look like phone numbers or whatever you disguise them as. Try that with a Cryptosteel in your carry-on.
• Metal plate combo. Instead of engraving 24 seed words on metal (screams crypto), engrave the book cipher codes: 47-3-5, 112-7-2, 83-1-11, ... — same durability, but now it's meaningless numbers.

Honest take

Some of the criticism from last time was absolutely valid. Security through obscurity IS a weakness — when it's your only layer. But as one layer among several (different storage locations, passphrase, metal backup, flexible encoding), I think book cipher adds real value. The second book doesn't fix every concern, but it addresses the biggest ones: more book options, more encoding flexibility, and a version that doesn't look out of place for adults without kids.

Happy to answer any questions — and genuinely curious if anyone from the last post actually ended up trying the book cipher approach.
