So what is actually wrong here?
from what I understand OP is complaining that Bitvest is not providing good service for him, he should change site if he thinks Bitvest is not providing good service. maybe this post of his is to alert people. at last the owner of Bitvest will be able to come and explain what is happening if all that the OP said is really true or not. but one thing is clear: Bitvest is not a scam, although from what I understand OP wanted the payments to be instant, I don't use Bitvest so I can't confirm whether the payments are instant or not.
