Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoinโs creator, Satoshi Nakamoto, originally described the need for โan electronic payment system based on cryptographic proof instead of trust.โ Each and every Bitcoin transaction thatโs ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. Thatโs by design: Core to their decentralized nature, Bitcoins arenโt backed by the government or any issuing institution, and thereโs nothing to guarantee their value besides the proof baked in the heart of the system. โThe reason why itโs worth money is simply because we, as people, decided it has valueโsame as gold,โ says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
โTo the extent it is used I fear itโs often for illicit finance. Itโs an extremely inefficient way of conducting transactions, and the amount of energy thatโs consumed in processing those transactions is staggering,โ the former Fed chairwoman said. Yellenโs comments have been cited as a reason for bitcoinโs recent losses. However, Yellenโs assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.
