Currently, there are many altcoins that have low capitalization, but not all of them have the opportunity to grow higher, and vice versa, but before choosing an altcoin that has low capitalization, it is best to analyze and study in detail about the project, because the risk is very big, it's best to choose an altcoin that is in the top 100 market,
An investor does not have to check both of these things before investing in a cryptocurrency. A coin or a token having a low market cap doesn't necessarily have to have the potential to gain significant value in the future, and, a cryptocurrency ranked in the top 100 cryptocurrencies might not give you great profits during the bull run. So, don't look at such metrics before investing your money and go deeper into a project and its history before taking any decision since it's important.
A project that is new but has a great team and a vision that is visible and clear but isn't listed in the top 100 because it's new, this thing alone doesn't make the project worthless or not worth investing in. Similarly, a project that is in the top 100 but has been going downhill recently might not deserve any investment. That's why, it's always important to check every aspect before taking a decision.
