yea i know, from any wallet i can transfer BTC but i want at the wallet i do exchange of btc to usd and then transfer money to cc;
If you are looking for web wallets ,i think xapo and coinbase allow you to sell your coins,it all depends upon which country you are located,as i think there are restrictions in some countries,if you are looking for exchanges then you should verify your ID .
I myself think that coinbase is the best web wallet, it is very convenient for the user, not only support for bitcoin, it also supports ETH, and recently, it has been eyeing LTC. . These are the most potential currencies, indicating that developers are very interested in the user, although it is not supported in some countries, but it rarely occurs.
