No, and no again. The low price of a coin is not an excuse to buy. A low price can be important only if you own insider data and future manipulations are known to you.
The main factor for investing in a cheap token is the project itself. Don't put money in shitcoin. With them, there are even greater falls. You think that this is the bottom and you can buy, but if the project has no future, then the price may fall even more and in general it is delisted from the exchange.
