...I'm not sure if the 4 years cycle will be a thing anymore, we haven't had bull run ever since the last one, altcoins are stuck, maybe institutional doesn't trust these cons again unlike then when everyone can make that profit in less than 4 years.
The four-year cycle is determined by the period between bitcoin halvings, and in the current cryptocurrency market, this applies not only to BTC, but also to all altcoins. The dominance of bitcoin remains, which indicates that BTC enjoys the greatest trust.
