I am not sure what you mean. I can clearly see "Currently Bitcoin to vTorrent is not supported by CoinSwitch." written there. It looks like they just refer you to Bittrex, isnt't it?
No, they actually buy it for you on the Bittrex exchange, super convenient if you are waiting for an account and want it now. For coins with more exchanges, it also allows for choosing the lowest price it seems. Looks like a pretty cool project. Currently Bitcoin to vTorrent is not supported by CoinSwitch means that they don't have the supply in stock themselves I guess since popular coins offer the option to buy directly from CoinSwitch.
Thanks, that's nice to know. I've never used such services, as I like doing stuff myself, but I definitely agree it could be useful to many, especially now when registrations are suspended in many exchanges, and even for existing users of who want anonymity and don't wish to pass verification. I suppose CoinSwitch doesn't require verification by itself. Does it?
