In my opinion, there is not and cannot be a single approach to the issue of the duration of holding our cryptocurrencies. It is advisable to keep some coins or tokens for a long time, others only for a short time. At the same time, it is hardly worth setting yourself the goal of holding some kind of cryptocurrency, even the most promising one, for as long as 10 years. During this time, many things will surely change, including it may lose its value or even disappear from the cryptocurrency market.
