For those of you who gamble at offshore crypto casinos

You get sent your winnings to PayPal lets say. You sell it. You cash it to your bank.

What are my tax obligations as a person who makes less than 100k a year. Couldn’t I just say the crypto I was sent was a gift or what?

I’ve lost much more than I’ve won in my lifetime and ethically just don’t really care.

What do you all do tax wise who don’t gamble at DraftKings, mgm, legit casinos, etc. only crypto from a random wallet being sent to yours
