Buying a coin because it is cheap is not a wise thing to do, the reason being that you might not know what the lowest price could be. It is possible you buy and the price continues to fall. So instead of buying with the price in consideration, buy the value. A coin with value will have good products. A product that is needed by investors and those who would like to use it. Although, you might be fortunate to buy it at low price, which then increases your chances of having more profits.
A wise investor will not buy cheap coins just because it is cheap, they buy coin because of the platform and the support that they are getting from the community, only pump and dump group buy a cheap coin, because they will pump it in the future.
A potential coin in cheap price is what you have buy because no matter how long it takes to recover, it will become profitable. Buy those coin that will pump even higher than you imagine. Wise investors really won't invest on a coin just because it is cheap but they find the value of it on the market.
