ok so we need to trust them... damn, i did hope they destroy our ID after the checking...
I'm sure they need to keep your id in case of audit but I doubt it's 'on the internet'. I don't know who asked for the ID (Totem/Dolz, the exchange?, someone else?) but there are laws in the US and others that should protect your privacy. My guess is the exchange has your ID so you might try figuring out where the exchange is and what laws protect you.
I have what's left of my crpto in US banks & brokerages (Robinhood and Sofi) so they had my identity in order to open the accounts. Robinhood feels more than a little shady but it is covered by US laws so I'm not to worried about my privacy.
I don't even have the keys to my crypto so technically is being held in my behalf (and not insured). I was on a list for a wallet at Robinhood. I don't plan to use the wallet but was curious to see what a crypto wallet looked like. Not sure what if anything I'll do with the crypto but I am sure I wont spend it on NFTs.
I'm sure they had to get your ID in order to prevent or at least help detect money laundering and other possible crimes. I've read of ways to buy crypto without your id but the whole thing is shady enough without trying to circumvent what little saftey there is in the market.
