i have tried to swap from changelly.com recently from btc to eth exchange, i tired to exchange my .002 btc and it is worth of .03ETH. the purpose of that exchange is for my gas for erc20 token transactions from MEW wallet.but it took me more than 3 hours to wait but it is worth the wait because of my MEW gas, i had traded to tokens to etherdelta and i'm so happy for the unexpected amount.
This is my reason also why I want to convert my btc to ETH for me to cover the gas for erc20 token.
I converted already some of my btc to ETH in changelly but the convertion takes hours.
