Here is my opinion:
- Nowadays, many people are less interested in bank products.
- Many noobs entering the Cryptocurrencies market, and they only know Bitcoin, not altcoin.
- Venture capital also entering Cryptocurrencies and want to avoid tax.
In short the advantages you can gain in bitcoin is the reason why people likes bitcoin which makes them go crazy. Bitcoin can do a lot of things in as individual who wanted for help from a bitcoin. As per the advantages, more and more peope wanted to engage in using bitcoin, or cryptocurrency.
