Have any of you guys been asked by your bank about the source of funds in a recent transaction where you sell your bitcoins (or other crypto) and receive a wire transfer? Especially since the other trader is basically a stranger to you for the bank's purposes?
No, but you should not risk testing this with to many wire transfer transactions.
Limits and thresholds are different for each country and bank, and I don't think we can find clear information about that anywhere.
If there is a choice you should always exchange bitcoin for cash by using p2p transactions and decentralized exchanges.
Another alternative is to use crypto cards, but that also have different type of risks.
