Ive seen a few folks talk about massive spreads on the otc offerings etc. In this situation in particular, I think youre better off on the exchange CV. Imo better to seek value, accept the risk (bitcoin could go to zero), stick a bunch o limits out there, see what the market gives you, then do the best you can with what you have.
Ive not been paying much attention to other exchanges but as I said
earlier, someone got filled on their bids down to £6,200 the other day when the tarders
! That was an opportunity for anyone wanting to buy. It dont take much to do that when the books thin, by mistake or design, but you have to be guy at the plate with the orders out there to capitalise.
