Top 500 is still too wide and in my opinion not all of them are good to invest, also there are a lot of project are using fake volume to get more investors. I think, coinmarketcap rank can't be a good factor to invest in projects.
Even the 1-100 Own rank is still a lot that has the potential to fail if the research you do includes enough projects. it's better that you first pay attention to the large trading volume and also that the Projeck is already running. if still this development is not suitable if you invest for a long time
The best is better to do your own research of all the tokens/coins that u want to invest with.. Sometimes even if they are listed on coinmarketcap but on reality they are dead projects already... Look with the platform that has active team and achieve what is really written on their roadmap... A project that has a real product.. Also goes with active community and social media accounts... Those liked projects are really worth to invest with...
