I don't think many bitcoin users want their currency to become main. As for sure, we can't even dream about it for next nearest 10 years.
Actually that is true. We have our own opinion about this bitcoin as mainstream currency.
I dont agree also with that. I dont want to see bitcoin falling to the officials of the government and just using it to milk money for their own profit.
In some way, I want it to be a currency for the online world, I mean no more other option but just bitcoin.
Better than making it like a physical money.
