Sadly I regret to see alt movements, it's become very hard to understand. Because when a dump happens on Bitcoin price then we encounter an immediate action in major altcoins. Alts just follow the Bitcoin trend. But surprisingly when BTC recovers after a dump, then alts aren't following bitcoin trends but still dumping more. I am not a tech guy, so just follow the trend. But seems the trend also missing lately due to alt behavior. If always happen like that then most likely I will have to lose my portfolio again like last bull in 2017.
You know already that bitcoin controls the market flow. When bitcoin bull after some time , altcoins will grow in green and the bear happens the same way.
But your concern is the recovering of bitcoin does not show same for altcoins. This is not all altcoins. Top altcoins will manage to stable again, and low profile altcoins may not drive back to the point where it was because it is just a hype and pump coin, no strong team. Next time you need strong altcoins to invest.
