I think everybody can do long term hold, it doesn't matter if you are a beginner or a proficient market participant, just develop your own portfolio.
There's no exception on who can hold and who can't.
Everyone is liable to do their plan of long term holding whether with altcoins or bitcoin. As long as you have sufficient money to invest in to crypto's and your plan is just buy and forget that coin then you are doing it as a long term regardless of being new or not to this market.
