You know that Market Makers are used to creating volume and not necessarily making profits, right? You can do this and cannot always make profits because of the possible fees you will get. You can only have assurance sometimes, then if you are put into the wrong position, you will lose money for that.
Saying that you can profit consistently is a red flag. Careful.
Market maker can dive the price by volumes and buying all dump but he will sell it higher anyway , based on my experience he never trade for loses.
