When it comes to the ECB printing large quantities of QE money I say bring it on! The so-called asset based cryptocurrencies such as BTC are essentially receptacles through which the deluge of QE will flow trough. When central banks go on a buying spree, stock prices will go up and we know some of that money will find its way to crypto. Maybe not so much gold because gold is a thing mainly old people like to hold. When boomers kick the bucket their holdings will be in the hands of millenials who won't touch gold but buy crypto instead.
