>>60505387 (OP)Under most jurisdictions (check your local laws), this is considered an "overpayment of wages" or whatever, and they absolutely can demand repayment. The legal doctrine of unjust enrichment applies here, you can't legally keep money you didn't earn.
That said, they may write it off if it's small amounts. Either way, consult a REAL lawyer, not fucking 4chan. In the meantime, maybe put that energy into safer plays like goat on avax or some other memecoin instead if you're so interested in gambling with money, at least this way you won't get fucked unless you have shit luck and spend like a maniac.
