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.
AEX.com exchange is legit, is an exchange registered in the United Kingdom. As I heard (can't remember where) the owners of AEX.com exchange are the chinese from BTC38, but I'm not sure about it.
