Re: Steem tokens, not too sure about that. Since they stole the network and stole a lot of user tokens (including my own) it hasn't been a legitimate blockchain, no US-friendly exchanges will trade it. If any of the exchanges that still trade it don't require KYC, it's possible you could use a foreign VPN to access it. I am not up to date on which exchanges you could do that with though.
