This is all from the point of view of a decentralized, p2p, no kyc exchange. If you pay for bitcoin with an interac e-transfer, I have heard the bank has no idea where the money went, or at least does not know you bought bitcoin. Is this true?
Once you have bought the bitcoin, do the banks and the government know you own bitcoin? Do they tax you on that?
When you buy monero with bitcoin, do they know you now own monero, or are they just guessing that you do, in other words do they have proof that you bought monero? Do they even know you bought monero? I am eagerly awaiting an answer as I think these are fundamental questions.
Also, what is the advantage of using Bisq over other decentralized, p2p, no kyc exchanges.
The concern of knowing if the banks know that you've purchased bitcoin or monero or any cryptocurrency, they won't have an idea that you did. What they're going to know is that when you're starting to transfer cash out from exchanges direct to your bank account. If the banks in your countries are too strict if the transfers are coming from exchanges then that's how things will start. They might ask you how did you got the money especially if it's a huge amount of transfer all of a sudden. And for the taxation, it lies from the government's rule in your country but most likely you'll get taxed and they'll have the record from the exchange you use.
