Programming is the way to go, you can work over the internet for a crypto entity, or work on something big that we need but just dont have yet, like crypto chess, or wallet with friends list, you might make it big, and if your really worried about scammer then this will sort that out. You can provide a fair service that lasts and that people enjoy.
There's also buying it with cash, mining it, airdrops, proof of stake, games, high risk platforms (if your lucky) and ofc just holding onto it for next time. But I dare say programming is on top.
