Bitcoinâ€™s Price Was Artificially Inflated, Fueling Skyrocketing Value, Researchers Say (Published 2018)
transcript Baffled by Bitcoin? How Cryptocurrency WorksFrom Bitcoin to Litecoin to Ethereum, we explain how cryptocurrency transactions work. Thereâ€™s Bitcoin. Thereâ€™s Litecoin. Thereâ€™s Ethereum. So just what is cryptocurrency, and how does it work? Essentially, itâ€™s digital money thatâ€™s bought and sold online. Thereâ€™s no bills or coins. Itâ€™s not based on another asset like gold. And it doesnâ€™t go

Bitcoin is no longer the only game in crypto-currency townWhich could be the next digital coin to rule them all? IT STARTED as a joke. Dogecoin was launched in 2013 as a bitcoin parody, using as its mascot a Japanese shiba inu dog, a popular internet meme.

The trust machine
BITCOIN has a bad reputation. The decentralised digital cryptocurrency, powered by a vast computer network, is notorious for the wild fluctuations in its value, the zeal of its supporters and its degenerate uses, such as extortion, buying drugs and hiring hitmen in the online bazaars of the â€œdark netâ€.
