4 years for Diamond is a round date, but let's take a short look into the past for Bitcoin.
An interesting historical fact.
The project bitcoin started in 2008.
But February 9, 2011 (4 years after the appearance), 1 bitcoin cost $ 1, after which there was a long decline.
March 23-24 BTC reached parity with the euro and the British pound.
On June 2, the cost of one BTC was $ 10, and in a week it shot up to $ 31.91.
I do not want to grow here a direct relation with the growth stages of Diamond, but you will agree that there is some similarity in the dynamics of development
