Since this is so new I'd suspect it would be wise to let some of these traders establish their brand before latching on to any one of them (there's very few providers at this point anyway). Something to keep an eye on tho.
Definitely. I would wait for the Master accounts to establish trading history to determine the ideal account to follow. There is also the potential for manipulation in such an illiquid market as Bitcoin. It would be a good idea to wait a while before jumping in.
