Smart people can see the future. When they learned of Bitcoin and its technology, the appeal to the public and government, they can easily see the potential of this Bitcoin. And then they move their fund and invest on it since they believe it is always best to invest on a first mover as bitcoin is the first mover to decentralized blockchain.
I came to know vabout bitcoin in the year 2015 and I noticed bitcoin is price at 400 USD only but from the time last year halving happened and after that bitcoin price bumps to more value in the chart.
Especially this year we will find more adoption and price bump on the chart.
