I agree with your statement, storing Altcoins for a long time will make a person Rich by earning huge profits. but not everyone is able to do it except those who have excess money.
Those who have more money will also not be able to do it if their patience is not enough and not big, because it can only be done by those who have enough patience and also enough capital for it, and one more thing is that not all Altcoins can provide great benefits even if it has been held for a long time.
