Being a hodlr between easy and not,
but here I try to share about my opinion, what we have to know in the coin before we hold it.
first,
try to choose coins that have good history,
because basically the chart is repetitive,
example of a coin movement that has a good chart.

and below this is a sample coin that does not have a good history and the chart movement is monotonous and we must avoid this coin.

second,
see the github link account,
if the respositories are always updated, then the coin is worth holding, because the dev on the coin always works so that the project is always upgraded.
For example, an active Github link account.

and third is the social media,
if the social media is not active, I suggest not to hold it, but if the social media is active, the project can be an option.
those are some of the things I usually notice before hodl a coin,
then what do you think and what research do you do before investing?
