Probably i would buy and hold if the altcoins are dumped their prices in the market, buying is the best for me when their is dump of altcoins i can choose the best altcoins that have very promising to increase their prices in the market.
It is good idea when the price falls more you will get another chance for buying more coins. The more you buy the more you earn. Dont look the current bad situation of the market. It will not last for long. In the near future the prices will change. The trend of the market will change and the investment caps will go high and high. Just need patience and confidence.
