I am not expecting for most altcoins to see them have that price increase. Whenever the alts are dropping in prices, most of them are having difficulty in recovering.
That is what you'll see in the charts and that's historical. Maybe for some that it will work but for most, it won't.
Some good and top altcoins are also having that difficulty in moving upwards.
Such altcoins have a common reality of ending up in a
liquidity trap where holders have nobody who is willing to purchase the altcoin. this is quite the worse end result of holding an altcoin with no growth expectance, at a very low rate, some altcoins get delisted from top exchanges, tanking the remaining value entirely to nothing.
When there is no longer liquidity and volume in it, the investors or holders should expect nothing from it anymore.
As you said, they'll have hard time in selling the altcoin when there are no buyers but there's a lot of sellers.
So, with altcoins which is being picked by the holders as their lottery tickets they have to give that up because not all altcoins recovers after the bear.
