I am pretty sure, that this regulation will not affect Steemit. Or better say STEEM blockchain. Because it is decentralized with no authority to shut it down. So I feel comfortable also with my STEEM bag.
I think when more and more DEX will be on the field, there will be less and less to regulate. They might now only focus on fiat onramps and offramps, but in the time, when you could pay by some crypto (stablecoin, maybe the national e-coin etc.), there will be always ways to use your crypto somehow. Like Revolut or Wirex at this moment.
