Uquid has the lowest fees of them all, but they write bad English so I can't vouch that they are safe to use. Wirex has not lunched its free virtual card yet, it's still in the beta phase as of now. Cryptopay's fees are moderate and I've not checked out spectrocoin.
Yeah, it seem uquid not care much about languages. but i think it not important as far as i not read what they saying.
what we need from them is virtual card and service. so far. I still think uquid is best on market at this moment.
Hope we can get free Wirex card soon for test.
Cryptopay high fees
Spectrocoin scamming their customer did you know that (you should take care of them)
