Even then I will ask to the communities or the polygon investor will think that it will be good idea to hold polygon for long-term or the best will be sell immediately after the recovery?
Let's discuss-
Apart from the fact that some altcoins can sometimes be very disappointing, I really think that polygon is going to be persistent and will do far well in the future compare to its current price. I have traded Matic when price was even more than one dollar and I still believe that with the low transaction fee of the polygon network, the coin can go above $2 in the future. It just requires patience for investors to be able to hold till then and also be aware that anything can happen to disrupt the project from archiving it's speculated growth.
Polygon has never been disappointing for some time now and I don't see it doing it now. I rate it as one of the best-performing altcoins in more than 5 years interval. It is the fourth altcoin I bought after some little investment in Bitcoin. There have been a lot of technical updates in the Polygon network such a network won't just crash irrespective of my guess that what OP said is just a shakeout i the network.
However, one thing remains the network is usable cheap, and fast. People should just stop trading the Polygon and invest in it for a long-term goal. If it's too much for them to handle then they should migrate to investing in another altcoin.
