Lets see here. We have central banks in almost every country. The only countries left with no central bank are Syria, North Korea and Iran. HMMMM They are all being attacked right now.
We have a brand new technology created by a mystery man that no one knows who it is. This technology also tracks every transaction made which will make taxing every transaction a breeze.
Not saying Bitcoin is a trap but we need to keep our eyes open and be aware.
If blockchain doesn't have a proof-of-work ledger, do you think we got this far today? Those countries that you are talking are having a government issue and blockchain cannot do anything about it, it is the government's job to change the mind of their leader but i doubt it will happen unless they start to change their system of the government.
