As a holder it's not healthy to avoid watching the crypto market from time to time, most especially now that we have so many new altcoins, you can't invest in new altcoins and not keep a serious watch on them because anything can happen, I've been able to pull out my money from a altcoin before it collapse because I'm on watch
That is why crypto/altcoin is different with Bitcoin.
Altcoins are recommended for short term holding since it's full of pump and dump scheme, it's why you need to look the market what will happen with your coins... just like trading.
When you missed the opportunity to sell at the peak, the price will goes down significantly. While Bitcoin even it's dropped, surely in the long run the price will recover and that's the opportunity to buy the dip.
Altcoin ownership I think is much better in the short term even I see someone who shares it in altcoin trading only for a massive 24 hours depending on the movement of the coins we have even with the slightest profit they will sell because it has reached the target.
Altcoins with a pump and dump would be made to create hype and it would be bigger to pump like that but I'm not really sure of a longer hold on altcoins.
Obviously bitcoin is only intended for the long term so not every time you look at the market every day.
