Hong Kong crypto exchange OKEx increased the maximum leverage 5x for trading pairs [$BTC]/USDT, $ETH/USDT, ETH/BTC, $BCH/USDT, BCH/BTC, $LTC/USDT, LTC/BTC, $ETC/USDT, ETC/BTC, $EOS/USDT and EOS/BTC. OKEx says the leverage increase was due to market demand, but some experts believe it was done to increase trade volume against top dog Binance.
