$PI If buying could make you effortlessly and continuously make money, how could it be possible? If that were the case, who would sell? No matter how much it's worth, as long as it keeps falling, someone will keep buying. During this decline with ups and downs, short-term traders will be buying and selling. As long as you believe that as long as it's a public chain, it won't die, holding on without cutting losses makes you the winner; holding on until profit is achieved makes you a rookie.
