Not ignorant at all :). In that example, yes. I’m not perfectly sure, but I think that’s the case IF that’s how everyone else withdrew before you. I.e. in what increments they withdrew (as seen in the difference btwn 1k and 10k chunks).
I think you risk more now beacuse centralised exchanges send rapports to gouverments. Soon you will pay taxes on profit on your trades. As a person to person trade does not involve business activity. Soon trades will be made person to person like this Dether exchange PTM public teller machine.
