The author and the sole controller of the cryptocurrency market's 4-year cycle is Bitcoin. Technically, the fate of the altcoin market trend is determined based on the BTC trend.
I would be more careful of the altcoin market if I were you because a lot of shitcoins are mostly created this season under the hype and bullish trend of BTC to fool newbie investors/traders. But if you must choose altcoin you can go for the altcoin GrayScale added to their ETF.

Having said that, the market correction mostly happens a year after the rally market, and I expect the next correction to happen around 2025 Q4. However, it will be hard for most crypto to experience big market correction due to institutional banking, and world investment companies (Grayscale, BlackRock, etc) accumulation.
