Bitcoin Oversigt
Bitcoin (valutaforkortelse: BTC eller XBT) er et online betalingssystem og en virtuel valuta. Selvom bitcoin som betalingsmiddel kun accepteres ganske få steder, er den populær som investeringsobjekt og er verdens mest kendte kryptovaluta. Det blev opfundet af den anonyme Satoshi Nakamoto, som offentliggjorde sin opfindelse i 2008 og efterfølgende udgav systemet som open source i 2009. Systemet er peer-to-peer, så brugere kan indgå i transaktioner med hinanden uden mellemled som pengeinstitutter eller centralbanker. Skabelsen af nye bitcoin og godkendelsen af transaktioner bliver i bitcoin-systemet håndteret kollektivt i et netværk af computere ved hjælp af kryptografiske algoritmer. Som følge heraf er bitcoin i modsætning til traditionelle valutaer hverken reguleret eller underlagt beskyttelsesregler i lovgivningen på dansk og europæisk plan. Økonomer og bankfolk har gennem tiden vurderet bitcoins fremtid til at være yderst tvivlsom og sammenlignet den med en lottokupon. Den danske nationalbankdirektør Lars Rohde advarede i december 2017 mod at anvende bitcoin, som han hverken fandt velegnet som betalingsmiddel eller investering. Han kaldte den digitale valuta for en økonomisk boble, der var ude af kontrol, og sammenlignede den med den hollandske tulipanboble i 1600-tallet, en af verdenshistoriens kendteste finansielle bobler. Selve teknologien bag bitcoin, især den såkaldte blokkæde, anses dog for at være lovende i flere økonomiske og finansielle sammenhænge.
