Bitcoin ETFs approval makes itself expensive along with rest altcoins. As altcoins follows Bitcoin movement, that's why a massive growth have been seen in altcoins industry. Top altcoins are become so expensive. But others altcoins are Still underrated. Maybe they are waiting for pure bull run in altcoins sector. After that, they might be touch new record again. And top altcoins will be more and more expensive then now.
i think not far from now altcoins will rise up,look at btc price it is in bull season and anytime of the day some of the altcoins will also rise because it always follow the bitcoin trend, some top altcoins are now slowly rising example is the bnb and ethereum,so we can expect the altcoin season maybe this third to fourth quarter of the year.
The current increase in the price of Bitcoin is temporary as it is again due to ETF. The bull run that everyone has been waiting past halving has not yet started. When it starts we will be again seeing an overall increase in the price of altcoins as they follow the path of Bitcoin. As of now whatever rise we are noticing is temporary and another price correction is on the way.
