This is a clever display by the G20. Declaring that bitcoin does not pose a threat to the world financial stability then pumping up bitcoins value afterwards. It's a subtle way of them saying that bitcoin may be independent, but they are the final arbiter of it's value.
Again, I hope people will stop looking at bitcoin as an asset and use it as a decentralized currency the way it was supposed to. The world will be better off that way should we start using bitcoin the way it is supposed to, not hoarding the coins which results to the current wild speculation of it's price in the market.
I really think we should use bitcoin as a currency and the way it will be useful for all of us leading the fast and secure transaction that it's services has always provide us, But can you can out the potential adoption that other people had been doing with bitcoin as an asset and the way whales are holding them, I really think that we can not say to other people in what they have to do with their bitcoin that is their own decisions to make.
