Another way, that I think will happen:

• get some developers and pay them to create crypto coin that way we banksters want: unlimited printing by us, with total transparency: who does what and where and how...

• when finished and tested and ready to deploy, put it into operation and tell your minnows (most important governments and politicians around the world) that they need to forbid by law any other currency but this, our, real one. Crime if caught must be punishable 2 times, 3 times more than say for getting caught with hard drugs. Only one crypto currency is allowed from now on.
