Well if I understand correctly the bank bail-in is supposed to convert all bank issued bonds to "then worthless" shares. Turning dead banks to zombie... IIRC bank bonds are owned by the likes of ETF, mutual funds, pension fund, insurance company asset so it is just a round about way to ding all savers.

I think crypto is not a bubble, many more will be fleeing the sinking fiat/banks.
