Bought BTC in 2014 (can prove fiat to crypto) and converted it to ETH, altcoins, and back to BTC. Haven't traded much overall but when I download the CSV files from exchanges those are huge – as you know, some orders get filled by many smaller transactions. Also, some altcoins have staking, airdrops, etc. It is really a mess to make sense of it. Heck, even myself I'm lost trying to figure out the path!
I'd like to cash out some of the crypto I hold and it seems Swissquote is a good option. In order to prove the source of funds, I could send them all the CSV files from exchanges with thousands of rows, but would this be enough? I would like to avoid the situation that I send them my crypto, and they freeze it for weeks until they decide.
Has anyone gone through the process of proving the source of funds? What do they usually ask for?
