Need your altcoins exchanged to BTC or any other coin, but don't have an account on an exchange?
Let me exchange them for you. I can exchange any of the coins available on bittrex. Visible here:
https://bittrex.com/home/marketsCharging 5% commission for exchanges under $100 ($5), 2.5% for exchanges over $100 (minimum $5 fee).
Transaction fees both ways are to be covered by you, I'll sell at current market price, or I can set a sell order for whichever price you want if you're willing to wait. Bittrex charges 0.25% fee per transaction.
