Been with Coin Wallet just over a month and have doubled my investment. My experience of buying and selling using the wallets and my debit card has been a positive experience to date. I have not had any cause to contact customer service either so I'm unable to comment on this service. I hope I won’t face any issues in future. All my trades are made in the exchange built-in the wallet. You can exchange all available ERC-20 & 23 tokens.See full review
