The reasons you mentioned are objective, but from my point of view, it is related to not losing money but it does not talk about your profit making, which is the basis for depositing on the platform. You need to know about trading volumes, orders to buy and sell, whether the platform has defrauded anyone before, And others.
in my option, I was using one of the platforms for anonymous token and sudden surprises by turning the entire trading volume to zero, which means losing my money.
