If you want to invest through the stockmarket, I'd go for the marijuana industry and the related biopharm companies that are coming up with medical uses for marijuana. It's a relatively new industry and saw it's first huge bull run at about the same time as bitcoin did, so it's now stabilizing and getting ready for the next stage. There's a good firm in Canada called Aurora that is constructing a grow operation the size of many many football fields that did well last year and looks like it is worth getting back into. The Canadian government approved it and the industry is in the billions, so there is good reason to be involved. And besides, it's better now that kids don't get thrown in jail for something so silly.
