Bitcoin emerged in 2008 shortly after Occupy Wall Street accused major banks of misusing borrowers' money, deceiving customers, manipulating the system, and charging expensive fees. It was the concern of the Bitcoin pioneers to give sellers the responsibility to eliminate middlemen, remove interest fees and make transactions transparent in order to prevent corruption and lower fees. So a decentralized system has been created where you control your funds and understand what is happening. Bitcoin has come a long way in a relatively short time. Companies all over the world accept this currency, from REEDS Jewelers, a large jewelry chain in the USA, to the private hospital in Warsaw. Billion dollar companies like Tesla, Dell, Expedia, PayPal, and Microsoft do too. Websites promote it, publications like Bitcoin Magazine publish news, forums discuss cryptocurrency and trade in the coins. It has an application programming interface (API), price index, and exchange rate. Problems include thieves hacking accounts, high volatility and delays in transactions. On the other hand, Bitcoin offers people in third world countries a very reliable way to pay and receive money.
