Although I agree with HODL crypto, I don't think that all crypto should choose HODL, because I don't think most crypto has any preservation value and potential.
I would agree with this.
IMHO, if there's a potential use case that would emerge with a certain coin, thus increasing it's price, HODLing is just fine.
On the other hand, not many seem to have such (potential) use cases, so perhaps they are much better for daytrading (or weektrading xD).
Been hodling few coins for almost 2 years and I know some people have been hodling for much longer.
The key is to invest amounts that you can almost immediately forget about. Like, for example, going out. You go, buy several drinks, forget about that money and move on.
If you can do that, it's sooooo easy to HODL.
