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.
I am happy at this post, when i read it, i was like 'at least someone is thinking like me', almost everyone attaches the total worth of a coin to its price and not its useabilty and application which is not fair i believe. so thanks for thinking this way, i believe blockchain tech needs people who think like us
