Today, more than 4,900 cryptocurrencies are listed across different exchange media. However, Bitcoin, Ethereum, and a few other major cryptos are the only that reach mainstream media. Market cap refers to the size of a company. Cryptos with a higher market cap is less vulnerable to wild volatility and manipulation while cryptos with a smaller market cap can be manipulated by large holders. Choose the crypto that presents less risk.
It is easy to ignore trading volume when you are dealing with crypto such as Bitcoin because it is highly traded. However, when you are dealing with altcoins with smaller market caps, you need to investigate how many units are bought and sold daily.
Higher trading volumes point to increased interest in the crypto and make it easier to buy and sell. If a digital currency has very low trading volumes, it might be a failing project.
