Solana wasn't alone which had Such downfall record but if you search about some others top altcoins like matic, dot, link, ada then you'll found same statistics after bull end. Besides if a altcoin has potential then there's no problem if it dumped a lot or goes dip cause somehow it'll be recovered and so was happened for solana. After that, it touched almost $200 something and still expensive. And people believe that it still has space to grow more in upcoming days
It had already started its bull run and just as what you think, we're on the same page. Once an altcoin moved a lot already, the money that was on it are already taken out and moves to another project as this is how the altcoins market works. I don't think that there will be more to its move not unless the peak of Bitcoin is made and there's a new flow of money going in to the altcoins. But I'd be settled with that and always believe that once an altcoin moved a lot just as its moving to a new ATH, it's not going to make another series of it.
