Thats the reason i sold all my bitcoins. I beleive in cypto tecnology, but sooner or later a Bitcoin Private Key will be stolen by bruteforce and the market will lost its value.

That's the reason I sold all my fiat. I believe in monetary technology, but sooner or later a credit card number will be replicated by bruteforce and the market will lose its value. Incidentally, a 16 digit credit card number has only 10¹⁶ combinations, whereas a bitcoin private key has over 10⁷⁷ combinations. So for every possible credit card number in existence, there are 10 trillion trillion trillion trillion trillion possible private keys.

If you are worried about the security of your bitcoin private key, then you must be utterly terrified about the security of your fiat!

And what algorithm is that exactly? They always talk like one exists but I havent seen it yet.

I'm also not an expert on the subject, however the one most commonly talked about at the moment is Lamport signatures, but probably only because they are the most developed. They have a couple of disadvantages, however, most notably their size, which effectively precludes them being used in their current form. There is plenty of researching going on in this area though, so I suspect the algorithm we eventually fork to is one which is still very early on in its development.

The biggest difference between Credit cards and Bitcoin is that you can bruteforce Bitcoin offline, which you can't do with credit cards that need to go through cc processing companies that will block you immidiatly
