There are several important factors:
- The idea behind the project/coin/token. Is it really needed? Is it solving a real problem and will it be used in 3-5-10 years ?
- The team behind it. Even if you have a great idea if you don't have the knowledge to make it reality you don't stand a chance.
- That's more of an opinion than a statement,but we,at Staking.com, believe the future of coins/tokens lies with the PoS. PoW is proving to have too many issues to solve and more and more new altcoins are using PoS or at least PoW/PoS hybrid.
