Maybe they are skilled in game development, just out of school --practised by scamming or hacking some poor bloke of his cryptocurrency.

Joking.

A more plausible situation could be that these were the folks who were able to snag 5 BTCa day from a faucet back in the beginning days of crypto.. Now they've cashed out and are obsessed with crypto, and are skilled in game development.

Joking again.. but who knows, something close I imagine :p
