In fact, the altcoins market is influenced by several factors one of which is the social media hype. This social media hype has been quite effective in the past few years especially in the meme coin community. The altcoins market has also started to rush due to the bearish and bullish trends in the market. I think it's more hype because they start with some famous old projects or famous people. Inside this the community of the exchange and the creators of the project are involved due to which they manipulate the price and make it skyrocket. Those who get caught in the net of this hype will lose a lot of money.
An event has less impact to drive altcoin compared to the Bitcoin's trend. We're now having a big red candle on Bitcoin, which is enough to push majority of alts to go down around 6% - 10%. Some alts may suffer more decrease due to the volatility.
I admit there was a manipulation, but it can't affect whole of alts in the market. The token such as LAB, Billion and Siren are the best example of manipulated tokens, but the patter is always jumping from one to another alts.
So i think Bitcoin's trend has greater impact to influence all of alts. When bitcoin recovers from 64k to the 81k, there have been massive surge happening to the alts too.
You would aware of it if you're always carefully watched the market.
