The whole scenario is completely different from the recent bull-market due to institution's involvement. Whenever there is a price correction, they jump in to buy more. This might last longer than everyone is expecting, no one can tell how high can prices can get, everyone is left out in the dark because the market can drop anytime soon and when it drops it will drop big time for sure.
Right, there are so big players today, not individual but huge companies like Tesla who recently released the official documents that they have invested $1.5B in the crypto market. So this is very different bullrun, unlike 2017.
So this might really be longer than we expect, like the four year cycle, it could last for six years or even more as more investors are now going full crypto, even banks we hated bitcoin is not thinking ahead because of Tesla's news.
