> Then you have stuff like BIP39 protecting people's money (cryptocurrency) that can be cracked for $350/hr on GPU rigs
This doesn't appear to be true (in the sense that yes it is feasible to crack 4-word BIP pass phrases, but all wallets that I'm aware of use at least 6 words, which is estimated to take 11 years for a hypothetical ASIC cracker)
Perhaps you are meaning this attack where someone was able to brute-force 4 words from a 12 words phrase. It matches your $350 cost, but of course is dramatically different to "cracking BIP39": https://medium.com/@johncantrell97/how-i-checked-over-1-tril...
