WCT, DEXE, DEGO, and MASK are all managed by the same market maker. There is a strong possibility that the market maker believes there will be no bull market ahead, and they have started to sell off aggressively and stop participating. However, if altcoins continue like this, with frequent abrupt sell-offs, it will only lead to a vicious cycle for altcoins, making everyone increasingly hesitant to buy altcoins. Funds will become more concentrated in Bitcoin, and the future market trends for BTC and altcoins will diverge even more. It's possible that Bitcoin could rise to 200,000, yet the altcoin season still does not appear.
