So, if you are looking for cryptocurrencies under USD 1, then penny Altcoins with high potential is what you can invest in.
Please do not decide on the price of a token/coin whether you buy it or not.
The price says exactly nothing about what the potential increase in value might look like.
This is a beginner's mistake, like "Why buy Bitcoin for 10k when I can also buy Bitcoin Gold for 25$. Bitcoin is Bitcoin, right?"
