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.
very correct with what you explain ... that buying when cheap prices is not an appropriate step to be done by investors or traders ... but many people do that, because they will predict that the coin will rise again ... even though the fact is that the coin price is falling even further than the previous purchase price ... so my advice is don't look at the cheap, but pay attention to its needs ...
