something is total wong man. Blocktrades is using the higher Poloniex price which is giving me a sweet deal using Bittrex and running SBD through to BTC and LTC!
My hope in sharing this is that someone at blocktrades will see this and update the code to check prices on multiple exchanges to avoid being vulnerable to this in the future.
so,using poloniex now not safe
Please use other trader.
Good! Keep it up
