farming isnt worth it unless you have the budget for 10+ towers, 20+ gpus in the market(sli), and the electricity bill.
next you want to see which cryptos have a good backing, good developers, their roadmap etc : (tell tale signs between the trash and unicorns) --> every crypto has a whitepaper, read it if you're serious
if you're a nerd you can day trade which is VERY time consuming. if you're like me: find some longterm cryps you like, test them out. FIND ICO DATES, read their whitepapers, and if you're lucky you might land a high player or overvalued coin which u can then cash out or keep faith in.
