I think you are jumping the gun a bit. Normally people do not rush to register just because they are told about a crypto exchnge. Actually, as many of us are fairly ignorant, we need a lot of questions asked for us to reach the comfort zone of taking action.

btw - @xmauron3 - are you involved in the crypto market (in the coding sense, not in trading, which you have already mentioned).
