If the capital pool is too small and the transaction volume is even smaller, you should not put too much money into the operation if it is really a pity not to buy at the bottom.

Otherwise, it will become a game between you and yourself. It is easy to buy and raise the price of the currency, but when you want to sell, you can't find someone to take over, or there are not enough people to take over, which will directly lead to not being able to sell it, or not being able to sell it completely.

The price will fall as soon as you sell it, and it will fall again if you sell it again. The price of the currency will never reach your instant selling price.
