People get the "bug". They stay up late way past their bedtimes falling down a rabbithole of youtube videos explaining 'impermanent loss' and 'ERC-721 vs ERC-1155 standards'. They're reading semi-technical whitepapers because someone on the internet told them they have to DYOR ("do your own research") before they dump their coin into a financial site run by anonymous @ handles with promises of 1,000,000% APY. For individuals with high risk tolerances or the extra cash—usually men in their 20's—the risk/reward payoff is totally worth it. When a typical bank run by suits offers 0.5% APY in a savings account, why not ape (invest without research) your 401k into a bag of low resolution sprites?
