No protection against theft, insane energy consumption.

you mean the same protection as cash and a fraction of the energy cost of all banking / visa / mastercard with an economic incentive to use renewables.

dont forget protection against theft inserts someone else to each transaction

		That's an obvious flat out lie, crypto consumes much more power than the banking system, because of course it does. It literally relies on proof of work, through arrays of GPUs pointlessly crunching numbers. And that's just to handle a fraction of the number of transactions the banking system does. It's estimated that Bitcoin alone uses up as much power as an entire country: https://www.polytechnique-insights.com/en/columns/energy/bit... And how many people use crypto again?
