Thanks @skycornish. I don't know if it's the best way, but what is working for me is a balance of cloud mining, with some partial reinvestment to keep it producing and extend the contracts, and some careful position based trading. I try to ignore the volatility (not easy yesterday, but thats precisely the time not to panic) and focus on whether the tokens I'm trading solve a specific problem or have some other quality that makes them unique. Here's an interesting article on factor analysis that might be useful for you:
