If you are really willing to earn you can actually both easily, you can invest your money depending on you on how you gonna invest it, either you can invest in different coins or just one coin but I really suggest invest with bitcoin even tho it is a short-term but then I also suggest with long-term investment. As I said you can also do bounty campaign while investing which is not really hard to do, I mostly do bounty campaign and I'm investing for long-term.
