Bitcoin is an electronic currency that is not in the hands of any government or bank. Instead, it is dependent on peer-to -peer software and cryptography.A public ledger records all bitcoin transactions and copies are kept on servers around the world. Any computer available can use one of these nodes. The decision on which currency is held by who is achieved cryptographically, rather than via a centralized authority such as a bank. Each transaction is broadcast across the whole network and shared between all nodes. Each block gets added by the mining network. It's bitcoin's official book of account. Like you would keep the coins you have in your physical wallet, virtual currencies reside in virtual wallets which can be accessed by client software.

The time of travel is gone from its source. It is believed that the Old French term travail means "work". Merriam Webster says that travel's initial use was documented around the 14th century. According to the Merriam-Webster Dictionary, this word is derived in Middle English Travailen, Travelen (which is a reference to struggle, labor, travel), and Old French Travail (which means working with a lot of effort and toil). The word travail is still employed in English to refer to fighting. Simon Winchester, in The Best Travelers' Tales 2004 says that the word travel is derived from an ancient Roman torture instrument called tripalium. This could reflect travel difficulties in the world of antiquity. Modern travel could be any easier, contingent upon the destination. Mount Everest, Amazonian rainforests, extreme tourism and adventure are among the most difficult types of travel. The method of transport can cause travel to be more difficult, whether it's by boat, train or cart.
