It's true, patience is the key to success in long-term investment, because there will be many temptations on our way to holding coins for a long time.
The proverb says "Holders are Winners” is not impossible when you hold top coins and other potential coins, the top three coins are coins worth adding to your portfolio for the long term for low risk and reliable price recovery even in the long run. I only set aside 35% for other altcoins for short term profit trading.
We need to recognize the difference between a useful advice and something that can ruin you if applied incorrectly, holding for the long term is widely recognized as one of the safest and best ways to invest and make profits, however this is only true if the projects in which you are investing have very strong fundamentals and in this market the number of projects like that are incredibly limited and as such you must be very careful with the kind of coins you decide to hold for the long term.
