I started using Steem a little while ago when it was around $1US. I wasn't sure how to buy Steem at the time as I didn't use the exchanges (I used eToro until they had to stop services to Canada). Anyhoo I'm in now. I think their Steem dollar, etc is a bit complicated for the average Facebook user so hopefully that will improve over time, even the private key login stuff. Hope it doesn't stay at the level of something like Google+. I seem to like coins that I can at least use and receive ie a currency like Steem and things like Bitcoin to buy things eventually, versus Ripple token used by banks (why should I own that token other than hoping it goes up).
