There is a lot of shilling lately (again) with "the flippening" event happening. Ethereum has created a new market which is basically 99% scam tokens, rugpulls, pump and dumps and NFTs which are probably used for money laundering. Anyway, the thing is, there is definitely if a demand for all of that, even if it's all based on a platform that's not decentralized.
So to the point: Would you quit if a centralized shitcoin managed to surpass Bitcoin in marketcap? At that point it would be clear that entire space is a joke. Bitcoin would still march on as usual, but it would be just sad to see people putting their money on shitcoins rather than on the only actually decentralized blockchain worth anything.
No I'm not instead i will accumulate more and will take this as advantage as the price will surge down so low and i will be in discounted value.
after this surpassing Bitcoin will experience some fall but eventually recover and may climb more than what it has when being surpassed.
remember that Shitcoin has no place in this area but just a pumping material.
