I took a 5-figure bitcoin payout from a sportsbook, had it sent to my bitcoin wallet, and then initiated a large sale. My bitcoin wallet contacted me and told me they want to talk to me, and know the source of the funds, before the sale will be completed and the funds will hit my account. In the meantime, I don't have access to that funds or the bitcoin. My question is, when I talk to them (assuming that's my only course of action), can I tell them the truth? Or will saying the source of the funds was a sportsbook payout cause issues? Thanks!
