The hype didn't last a long while. As for the XRP's latest case in winning against SEC, that hype only lasted for a day which we see a tremendous temporary growth of it's coin and so as the others like Bitcoin, Ethereum, etc.
But on the following day it didn't maintain the hype as we see a pullback.
If you are smart enough of this scenario, you would have taken profit that easily rather than being greedy unless you are thinking long term of the coins like BTC and ETH.
It's only been two or three days since the resolution of the SEC lawsuit, it's extremely early to make such assumptions. Also, it certainly did not last one day, XRP's price was less than $0.50 before the announcement that they won the lawsuit. It's now trending at $0.75, with a 60% increase in the last 7 days. On top of that, XRP surpassed BNB in market cap, and this is only the beginning; that's not insignificant at all. I'm not sure how it'll progress in the future, but so far, it has made decent advancements so far, which is positive, both for its future but also for other altcoins that were labeled as securities.
