I always wondered what is the problem for BTC to be finally adopted in the wide range of business, I was expecting at least a great adaption in the online business but even so, what stops business from adapting BTC, the volatility? The low rates of adoption? Or maybe a lack of propaganda? BTC is so great and I really wish I could use it in more places IRL!
I suggest you take some time and go through the whitepaper of Bitcoin, I believe it will give some idea behind the main purpose for the introduction of Bitcoin and blockchain technology. Decentralization is the basic principle running the Bitcoin Blockchain and the change in the market value is just the nature of a decentralized system.
