what if i found some money lying on the street? i can't gamble with it because i don't know where it came from?
what if it was an anonymous donation by someone? u know someone got rich so they rained a few thousand dollars away?
what if i was cam-whoring and someone send me money to buy nudes but they don't want to send me source of their funds?
what if it was cash gift from your grandfather? is he really going to issue u a donor letter explaining why he gifted it to u and where he got the money from?
what if ur parents died and left u some gold? no wills necessary because ur the only child? and they're antique and u sold 'em and got big bucks? how r u going to prove the source?
what if ur collecting dust from faucets, giveaways, collecting shit-coin bounties, shit-coin airdrops, arbitrage trading, microtasks, staking, etc. u can't keep track of all these?
there are literally 100s of profession where u receive cash payments and there is no paperwork, so does that mean u can't gamble with it?
this is all just bs and ways of confiscating people's money by exchanges and casinos. if they're this diligent then they should ask these questions before allowing the player to deposit the money.
why don't they say we won't allow u to play if u can't provide the source of your funds? it is only after u have won and try to withdraw that they get so worried about these things.
