Cryptocurrency is the end of central banking because with it you don't need any third party.
That is called wishful thinking isn't it? Cryptocurrency could actually disappear faster than many think. The weakest point of crypto is also its strength.
The lack of control. Weakest because the lack of control makes default so easy when wallets go lost, "get hacked" or else. Once trust is lost BTC and all other will loose value over a long period.
