Good post! Anyways, if bitcoin dies it won't kill crypto, and most certainly something can replace bitcoin very fast. Easy example, Litecoin, just like bitcoin but without all the drama. Another thing to consider is that, when quantumn computing becomes a reality, most blockchains will become useless/not safe without an update. There's a few projects already, that could potentially replace bitcoin in the future, quantum resistance included.
Anyways, cheer up! Crypto won't die on August first! it might just crash and burn, but that's all.
