Yes it is true bitcoin is becoming a global currency, meaning you can transact to different countries it's easier since you don't need to convert your local money to their local moneyBitcoin is an open-source, peer-to-peer digital currency that relies on the worlds first completely decentralized digital-payments system. Until Bitcoins invention in 2008 by the unidentified programmer known as Satoshi Nakamoto, online transactions always required a trusted third-party intermediary, like Visa/MasterCard or PayPal. Rather than relying on that third party, every transaction that occurs in the Bitcoin economy is registered in a public, distributed ledger, which is called the block chain. New transactions are checked against the block chain to ensure that the same Bitcoins havent been previously spent, thus eliminating the double-spending problem. The global peer-to-peer network, composed of thousands of users, takes the place of an intermediary. So, the term Bitcoin is used to refer to both the virtual currency as well as the decentralized payments network, and the dollar value of a Bitcoin is determined on an open market, just as is the exchange rate between different world currencies.
