The Banks, Google, Microsoft, Facebook, et al are likely staking major positions in cryptocurrency market. They do not want their drones entering the crypto market and riding the next boom wave.

The propaganda against cryptocurrency is quite akin to the Hamiltonian scheme concerning the Continental currency used to "pay" the soldiers of the Continental Congress. Having convinced virtually all of the former Continental soldiers of the worthlessness of the Continental currency, Hamilton and his cronies were able to purchase a majority stake in the outstanding currency for pennies on the dollar. Once he and his cronies amassed enough of this war debt, he championed full redemption, ie face value, of these currecies.

I suppose someone has to till the fields, cook the food, cobble shoes, work in sanitation, etc. but such obvert efforts to crush the poor are becoming tiresome to observe.
