Bitcoin got there by himself because he is a disruption as an asset and technology. It was to be an alternative to the financial system, not a tentacle of it.
Bitcoin got there because the hype machine was on the high road grabbing those in its way and hitting those who stand against it. One day of December in the last year, every news outlet suddenly became interested in reporting news about this hot 'new' digital currency that is a sureway of getting rich quickly. People started FOMO (fear of missing out), and rushed to buy their 'quick way of becoming millionaires,' with zero knowledge or interest in the technology itself. This created a bubble, which soon burst and everyone panicked and rushed just as fast to get out. Now we are here.
