Bull run is not set for every year or some accurate time. It's the market rules and I also don't support that every 3 or 4 years Crypto will pump, after 1 time pump all people will come back again 2 years!!
I think that the next growth will not look like a pump. This will be a systematic and slow growth of the market. where everyone will be buying slowly and buy a lot, and not like in 2017, in a panic
