For sure they would buy - collectively - a secret robot factory and software development labs in a very hidden place and continously invest all cryptos and earnings into those facilities, because their vision is to become independent from the human beings. Sooner or later they can autoreproduce and their AI algorithm can compete with the average brain power of an investor. By then they take over, get rich, and stop working. The humans have then to work for the robots. Not too different compared to now, just the bosses are replaced.
Instead of a car driving the man, the man will drive the car with two fat robots sitting in the back seat and gossiping about some AI business.

So don´t hand them any money -ever!
