everyone can do it, but this requires the patience inherent in more experienced people in my opinion
First anyone can holding long-term even newbies, my friends who just joined they buy bitcoin then leave it in their wallet to be hold for a few years, thats the proof. but to keep the long-term for altcoin is at risk, if the newbie wants to hold it then it is better to choose an trusted Altcoin like Ethereum, XRP, Dash, and etc..
