Of course yes, once you believed in the coins you invested that means in the future you knew to yourself that it will give
you a nice profit or savings. Just make sure that the coins you choose to hold in the long term or short term has a real
potential to increase in the future, or you did a research in it before deciding to buy em.
The best coins are always in a good trend and at a good rating so the volume is also very good, so there is no need to do too much research on coins that are already popular or well known, because they are all definitely good to keep in the long run, except for new coins whose potential is still a question mark.
As you said, its not required to analyze on best or top coins. However, I would suggest those who get into trading newly, yes have practice of analyzing coins. In the beginning, I too had a question which coins are best to invest. I had little amount to invest, so i searched for a coin which is less in price but have good potential project behind it. Later yes I found few best new coins like Matic in 2019 beside Bitcoin, ETH, BNB, XRP and etc . So Its is advisable for newbies to have practice of analyzing and keep updating themselves.
