As a trader, im also can't stop myself buying those altcoins at a double digit percentage price dump because that will surely turn out to be a profit after 5 to 7 days, depending on how the buyers react. If there is a dump then there will definitely a pump because traders have the same goal, buy low then sell high. The higher the demand, the higher the chance that the price will multiply. These are the usual cycle in the market and those with strong hands always win the battle.
