Although it looks like it is a limited toe-in-water at this point, having two of the riches countries on the planet join the crypto world is a great thing.
The global race is on, which countries will adopt a currency, which will use blockcahins as a logistics and process database is unknown, But what is known are some countries who have put their heads in the to hard sand bucket.
There will be winners and non starters in the crypto race, and what is clear is the global banking cartel will be working the MSM overtime along with their rules & regs departments to try & stop a horse that has not only bolted, but is off down the road.
