I don't really trade much anymore, I used to margin as it was fun but polo boned me one to many times and I don't trust Bitfinex and Kraken is in USD only and won't take my CC casue I'm not in the right country apparently. So all I usually do now is get BTC and buy XMR with it and try to hit the lows. I use polo until they demand KYC (I'm small potatoes) and Binance now and am looking forward to their decentralized Exchange.
