The BTS/EUR BTS/USD BTS/CNY is super relevant for on and off ramping and for tradingbots. Also keep in mind that a pair BTC/bitUSD BTC/bitEUR BTC/bitCNY not exist on any exchange. So there comes an alternative for Tehter. I also think that Lykke tries to get the customers from Bittrex (delisting BTS) and Poloniex (disabling issues of withdrawals). Smart move in my opinion. My friend text me that het opened an account on Lykke.
