They look phenomenal but so does ePayments and a lot of the other BTC/Debit Card/Bank Wire solutions.
The problem is these services have a LOT of trouble keeping their relationships with banks/MasterCard because they deal in BTC / overseas relationships.
These guys are regulated and look great but just like ePayments, MisterTango, and the other similar services, they have trouble keeping these things consistent.
Even CoinBase recently lost their accounts with Barclays UK.
People really, really underestimate how tight the global banking system has got ESPECIALLY for margin trading services.
