Coinsnex’s robot is integrated into the largest cryptocurrency trading platforms, including Poloniex, Bittrex and Binance. In the span of milliseconds, the robot makes bids and asks on the trading platforms, then selects and suggests the best available rate and displays the estimated rate on our site. The rates remain approximate until the transaction is actually made on the blockchain. The exchange rate at the time of a transaction may differ slightly from the estimated rate that you see when you begin a transaction.
