each btc possibly a sentient a.i in its own right
This is where I stopped reading. (ಠ_ಠ)
Can you hack a blockchain? No..
Anything humans made on this planet as far as software goes is 100% hackable.. This blockchain tech is 100% sentient.. It will hack you back if you try to hack.. Try it.. See what happens.. But I already know you have double digit i.q so I am not expecting an intelligent reply from you or most of the users on this forum.
