Bitcoin can be cashed and converted into the currencies of most countries. Users can use Bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, you can also use Bitcoin to buy real-life items. The biggest difference between Bitcoin and other virtual currencies is that its total amount is very limited and extremely scarce.
The monetary system once did not exceed1050,000 for four years, and the total will be permanently limited to 21050,000. The concept of virtual currency bitcoin was first put forward by Satoshi Nakamoto in 2009.
