1. Check the overall contents of the project such as a team, road map, white paper, etc.
2. Check various features offered by the project such as privacy coins or decentralized coins.
3. Check how valuable the coins are or compare with other more popular coins. if the coins have potential, of course have a multi-professional team & the volume of coins always increases.
4. To be honest, the best coins to invest are the top coins or have been listed in the top 10 at CMC.
5. I suggest you invest in established coins rather than looking for very young and newly planted coins to invest.
I say this because I personally don't have a high risk appetite, so it's better to invest safely ..
how about you guys?
Well this is a very resourceful points to take note before investing into any cryptocurrency project that you come across in this industry. But i must say that you left out some salient points as well. For instance you need to look at some developed products or working systems that the team has developed from their project. These bring very high liquidity to cryptocurrencies.
