The simple and short answer to your questions is NO.

There's no recommendations on how long to hold your coins. Hodling is based on choice and satisfaction. It has no specific or definite duration per se. You can hold for a week, months or years. What matters is how satisfied you are at the time of selling and that's when you realise you accomplished your mission.

You can as well hold forever if you're not satisfied with the current price until death separate you and your holding. Your next of kin will decide the rest if they have access to it. The decision as to how long to hold absolutely depends on you to make.
