One of the mistake I have made is that I always want to sell at the wrong time, because I'm always afraid when the market is going down. So I do ruch and pull out from the market to save myself from losing more. Market deserve you to be patient with her. For example you may buy a coin with $1,000 and after few hours you starting losing More than $300. be patient no need to panic the market will be back again, but it will take some time and it required some patient.
