FYI, bittrex isn't also a good idea, i had converted some btc worth about $60 into usd from there, the fee they deducted was almost 20 U$D!! it wasn't the exchanger site, it was deducted by bittrex :(

that's true and as far as bitcoin is concerned we all know that it always has very high tx fees, so if bittrex charge fees then it's normal.

what's your opinion about blockchain.info?
