Currently, if you want to buy any altcoin, it is very difficult. You can't choose an option quite easily. Also, the crypto market is currently volatile. In such circumstances if one wants to buy altcoin. So what should be the main focus?
I'm usually going after MVP (Minimum Viable Product) or partnership with at least one very well known player in the industry. Then I'm moving to tokenomics (is it adequate) and then to the team. The team should have at least working LinkedIn profiles (to more about them) and best-known in the community.
It's a risk versus reward game. If you don't have the time to do the diligence, stay with the Bitcoin.
