Usually the coins that do not return to the highest price or even the transaction value continues to decrease are coins that have no clear project or may be abandoned by the developer. I think there are a lot of coins like this and just in case, we should choose coins that are in the top 100 coinmarketcap
Even an abandoned project can pump for example dogecoin, I think its not always about dev abandoning the project or them not having the right idea, one thing I find common in projects that don't recover after a fall is that their community is reduced, so many people leave the project and move to something more exciting, lin conclusion alots of don't recover because they loose their community and they stop bringing something exciting to their members.
