Hmm, they told "from private wallet?". So it's possible to open there an account and send for example btc/eth directly from your private wallet like Trust Wallet, or MyEtherWallet (MEW), or any other to
Swissquote account? So we don't need any exchange like
Binance in this situation? I wonder at what rate they will convert the same btc to usd when enrolling. They will not have a questions about history of that btc? For example, if you bought them a lot of years ago and just hold them all these years. And really don't remember how did you buy them for example in 2016.
Please note that the question was about person who is not resident of US/Euro.
