I am a complete newbie here. I have been manually trading Bitcoin and other cryptos for a while and have been successful so far but I want to get more serious about it. I recently purchased the Bitcoin Trading Robot – Cryptocurrency never losing formula course and I am excited to get started. I have never used an exchange (other than Binance a WHILE ago). I currently trade using Abra but it will not work for this purpose. I was wondering if anyone had a good crypto exchange that they use with low fees that allows margin trading. I would be more than happy to sign up under anyone’s referral link if it helps them out too. Thanks!
