Drying machines makes life of a lots and lots of people more comfortable. Hundreds of millions is my lower estimation, maybe even billions (if we include industrial dryers used in textile and clothes-making). Useful segment (eg except speculation and illegal activities) of Bitcoin operation is consumed by millions of people tops, two or three orders of magnitude less. And I never heard about using dryers for drug trade.
