,The reason why majority traders lose money is because they buy in morning and want to price to go up in next few hours, if that didn't happen they sell their tokens in loss.
Having patience when trading doesn't mean you won't sell but keep on holding and waiting for the project to turn from being a loss to profits sometimes you won't get that happy ending that you're looking for. You aren't an investor that's supposed to hodl until the fate of the market changes. Trading is for short term and not long term hence while you still need to have patience with everything you do, know when to stop wasting your time waiting for something that won't change. Some projects has fallen because of some negatives news and haven't recovered since they started to decline in price. Be a smart trader and know when you're supposed to be holding or when you're meant to b smart about your decision and sell.
