it depends on a lot of things. Right now I'm just trading with around 100 tethers or sbd. so I'm not making much. But what I do is profitable and easily could be scaled up. I hope to scale my bankroll up to 10,000 tethers or sbd. Minimum to make profit is a 1% trade which is a piece of cake. Fees are .25% per trade, but you have to make two trades. (Buy then sell) It really depends on what im trading but 3-5% is normally where I try to sell just to be safe. But some people are making closer to 10% per trade. If you have a large bank roll you can make some crazy money if you know what you are doing. Once school settles down for me I would like to try and trade professionally (spend 3-6 hours per day). I am 99% sure that I can make my living off of trading. It would be a dream come true. Anyways hope that helps @enki74 sorry I didn't see your comment till now.
