You can invest in top-ranked coins, if you just because the coin is cheap, you can invest in a small amount of value coins. Every project looks promising, but we cannot tell whether it is really what it looks like.
There are only two options that can be done if you want to invest in current conditions, firstly buying cheap coins that still have the potential to increase such as Cardano, Tron, Xrp and Doge, the second is to buy coins that are slightly more expensive but still have the same potential.
