Can anyone in a nutshell explain why the price exploded and is it still worth buying or should I rather wait?
My advice would be to keep an eye on the blockchain for large transfers to known exchanges and keep an eye on AEX.com which appears to have added a RIC/BTC pair around the same time the pump started.
I have not tested AEX.com so I have no idea if they are legit.
I am not sure whether I understand your advice. Why would large transfers in this regard matter as you say?
