First, tell me how to determine the best altcoin in any particular year? Most people will say its price growth but I have a different opinion here. I think a project with larger and quality developments done in any year can be called best project of that year. The coin value can not determine a project good or note because there are a lot of things that can lower the price and one of the examples is whale market manipulations. So it depends on how much development Idena made in this year.
