Bitcoin being a digital currency and asset of investment applies in many areas of the economy base on the urgent needs for those in adoption for it uses, whenever we are having a desire for running a decentralized economy, then what should first ring in our minds is about bitcoin, because it has the solution of being profitable and applicable to different areas of the financial system as we may want from it.
Nobody would allow BTC to become the biggest nail for the "decentralized" economy.
I would be just happy for them to regulate the usage of it to be as free and wide as possible; that would be it, not that much.
Instead of saying "nobody would allow BTC to become the biggest nail for the decentralized economy, you should just say "the government won't allow BTC to become...". If I have the chance to, I would without thinking twice.
We don't need the government to make bitcoin more accessible and free to use, bitcoin has been used all these years even when the government kept threatening its ban. Bitcoin is decentralized for a reason and that is why it is free from the government's control. Saying the government should regulate the usage of bitcoin is like handing over powers to the government. All we need is a friendly environment for bitcoin to strive, not some regulations.
