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.
Only long-term investments should be made for the top altcoins in this market. If you hold a new altcoin in this market, it is suicide. A lot of altcoins have collapsed in this market and I know a lot of people are losing money trying to invest in them. The price of those altcoins has dropped 50-100 times in just a few months or a year, it's really scary to invest in new altcoins.
