If bitcoin makes move for price correction around 50 -60k most crypto will downfall specially those altcoins correlation. We can see more all time lows to those alts that has no big moves when BTC reach all time high (2024).
Personally I dont believe BTC can ever retouch $50k-60k again unless it's preparing for the next bearish cycle but I agree that alts in general will get it really bad, the thing is, alt got too much project with overly inflated valuation that could crumble overnight, although people consider recent retracement to be the end of temporary dips, but it's only that way for bitcoin, for alts in general it's still difficult to predict because even alt with no meaningful rally as of now, and majority of them already going back to bottom price, is already having big ALT3 1.36T market cap only a shy of 1.6T from its ATH which means, if BTC happen to enter bearish phase, most of alt gonna get wrecked heavily.
This is why investing in centralized exchanges is easier, because when you invest into coins and tokens at any CEX, you usually have a stop loss order as well, most of them have that feature now. So, if anything you invest into starts to drop badly, you could just put a stop loss order beforehand, and then get out when the price goes down that much. I have all of mine ready like that, well not all, I still have bitcoin and few other coins that I like to keep no matter how much they fall, but the rest.
I agree with bitcoin not going under 50-60 thousand dollars ever again, and I have few other coins like ETH and BNB and SOL which I trust, so I am keeping them as well and not planning on selling them at any moment, not even if they drop 50%+ from where they are right now, those are good projects and I am not willing to sell them even if they end up falling.
