The Great Crypto Crash of 2018 is well underway, according to the SMH. The MVIS CryptoCompare Digital Assets 10 Index extended its collapse from a January high to 80 per cent. The tumble has now surpassed the Nasdaq Composite Index's 78 per cent peak-to-trough decline after the dot-com bubble burst in 2000. The losses were led by Ether, the second-largest virtual currency. It fell 5.2 per cent to $US172.41 at 6:21 a.m. in New York, extending this month's retreat to 39 per cent. Bitcoin was little changed, while the MVIS CryptoCompare Digital Assets index fell 2.9 per cent. The value of all virtual currencies tracked by CoinMarketCap.com sank to $US187 billion, a 10-month low.
