Several hundred of these back-and-forths make up a block. No one controls these blocks, because blockchains are decentralized across every computer that has a bitcoin wallet, which you only get if you buy bitcoins.
True to its origins as an open, decentralized currency, bitcoin is meant to be a quicker, cheaper, and more reliable form of payment than money tied to individual countries.

Which could render bitcoin price irrelevant. Historically, the currency has been extremely volatile. As the total number creeps toward the 21 million mark, many suspect the profits miners once made creating new blocks will become so low they'll become negligible.
