CoinTracker does not provide investment advice.
That said, there are many factors to consider when making a cryptocurrency investment, such as purpose or utility of a coin, reputation of the team, white paper, code (how much active development is going on), which exchanges are listing the coin, is it a coin with its own blockchain or a token on an existing blockchain (e.g., ERC20 tokens on Ethereum), etc. Some of this information is available from the Prices page.
In general, avoid get rich quick schemes and don’t fall for pressure to invest NOW!!! There will always be more opportunities for investment, and it’s better to miss an opportunity that you don’t understand or aren’t comfortable with than jump onto a bad/scam investment.
