Overall I think this will be good for Bitcoin in the near term while probably getting worse for shitcoins for a while. Bitcoin's dominance now has a realistic reason to increase, as has been the case today breaking above a 2 year range it has been stuck in. While many shitcoins have little to no support right now as they break new lows, Bitcoin instead has a lot of support to the downside, between $20K and $25K.
Soon we will see the natural shift of shitcoin liquidity coming back to Bitcoin, especially when it starts rising again and shitcoins remain stagnant. This will likely be a good remainder of the year for BTC.
It is not affecting bitcoin like that because bitcoin is decentralized asset but some of the shitcoins or meme coins are centralized. So they open to attacked either by the government directly or it agencies. The liquidation is always there for bitcoin to move forward and any other altcoins that do well will also follow the trend.
While all very true, I think the reason we are seeing Bitcoin correct further (as opposed to move higher) is because speculators are selling crypto right now, and the reality is the majority of it remains altcoins.
So Bitcoin get's "wrapped up" in the selling fever, even if there isn't any logic to it or rational. Fortunately right now Bitcoin is very close (only 1% away) from reclaiming the majority of the crypto market, meaning it should be much less effected by what is happening to the minority of the market. At least in the past with high Bitcoin dominance as a majority, it becomes very unaffected and detached from the rest of the market.
Of course subjectivity this can simply be because Bitcoin is rising while shitcoins are flat or falling, as there is the momentum behind it, but notably this only ever happens when Bitcoin's market dominance is already relatively high at a clear majority. This is more of less the point of the term dominance, because it's based on how dominant Bitcoin is within the market and therefore how unaffected it becomes by it.
