Staying updated always is the main hodl strategy. Many projects have migrated to its own blockchain of recent and some persons have been left behind during these migration. If you want a long term hodl, hold few tokens you can always monitor their development progress.
Agree.. especially if you want to hold altcoin from new project do not miss any update from the project. But, i suggest hold only major altcoin. i'm holding only from top 25 in CoinmarketCap.
Hodling a new project will be difficult because even you are updated or you don't miss any updates from the project, you are still not sure if the coin that you are holding will have a good value in the future, that is why if you want to hold a good altcoin you better choose from top altcoins because for sure it has a potential to have a good value in the future.
