A well decentralized Altcoin and plans to improve the coin decentralization in the future could make me hold an Altcoin long-term. I cannot build a permanent base on project that is not truly decentralized.

I will also consider the coin Roadmap, expansion plans, developer's enthusiasm, project long-term viability, concepts, strategies to capture millions of users,  etc.

Developers ideals matter most in the end. .
