Regarding Steem, maybe you should have implemented Steem Dollar support instead... people would be more likely to spend their SBD instead of Steem for purchases.

I have actually used your service when you introduced BTC to PayPal transfers... and was really disappointed by the fact that you actually relied on eChecks and that took 3-5 DAYS for the money to actually be available on PayPal... there are much faster services, so I just went to one that did the same thing in a matter of a few hours and not days.

In the world of crypto getting fast response time is a key factor, so you should carefully consider what your target users are and what they want as there are many other alternatives available that may be more attractive for users to spend their altcoins at.
