I am still learning about all this so for me your post was a chance to learn more from you as well as from the other comments. I am not sure about the governmental regulations and their impact. It is a question I have as well. I am utterly lost when it comes to all the exchanges still so I have not even attempted to trade any of my steem. But I like this idea. One day I will get over my fears/be educated enough to trade. When I hear horror stories of coin being stolen on bittrex , it kinda scares me off till I have more knowledge of how to stay safe.
If it doesn’t offer 2-Factor Authentication then look for other exchanges. That would be my best advice. And try to read up on some of the crypto currencies that are out there to see if they align with what you believe in. Honestly I just buy-in with dirt cheap coins/tokens so I’m probably not a very good role model for this lol.
