Billionaire entrepreneur Elon Musk sparked a Bitcoin frenzy this week after his company Tesla bought $1.5billion's (£1.1billion) worth of the cryptocurrency. In a stock market filing, Tesla said it has "updated its investment policy" and is therefore looking to invest in "reserve assets" such as digital currencies, gold bullion or gold exchange-traded funds. The shock move drove the value of Bitcoin up to record highs after a turbulent month in January. Its value is now approaching the $50,000 (£36,000) mark, with the price currently sitting at around $47,000 (£34,000).
