Bitcoin came close to breaking the $50,000 barrier at the weekend and our Big Read on the cryptocurrency looks at its 350 per cent gain in the past 12 months.

Driving the price in the past week has been the Tesla revelation that it had spent $1.5bn on bitcoin. Then BNY Mellon — America’s oldest bank — on Thursday said it would start holding and transferring cryptocurrencies for asset management clients, while Mastercard announced it would soon support “select cryptocurrencies” on its network, allowing more stores to accept them as payment.

But analysts and investors say the main driver of bitcoin’s recent rise has been fears that central bank stimulus to dampen the economic damage of Covid-19 will ultimately ignite inflation. The hope of its proponents is that bitcoin is now becoming mainstream. “We are potentially at the birth of a new asset class,” argues Duncan MacInnes, a fund manager at Ruffer, a traditional, conservative UK investment group that raised eyebrows when it placed a $600m bet on bitcoin last year.

Bitcoin, the mother of all bubbles?

As for its opponents, Jonathan Ford argues in Inside Business that Elon Musk being a cheerleader for bitcoin is idiocy in terms of the environmental impact of producing it. Bitcoin miners are not interested in intermittent renewable energy, he says. Needing to run their machines 24/7, many site their operations in places with cheap coal-fired electricity.

The carbon footprint of bitcoin

In her latest column, Rana Foroohar says bitcoin’s rise may be seen as an early signal of a new world order in which the US and the dollar will play a less important role.

This is the belief in some parts of the investor community — that the US’s post-2008 financial crisis monetary policy designed to stabilise markets will give way to post-Covid monetisation of rising US debt loads. If the US government sells so much debt that the dollar starts to lose its value, then bitcoin could conceivably be a safe haven.

1. Apple talked to Nissan tooApple approached Japan’s Nissan in recent months about a tie-up for its secretive autonomous car project, but talks are no longer active, we’ve discovered.

2. EU news — UK data OK, Big Tech under French coshBrussels is set to allow data to continue to flow freely from the EU to the UK after concluding that the British had ensured an adequate level of protection for personal information post-Brexit.

3. US begins Arm probeThe EU is readying an investigation and now the US Federal Trade Commission has opened an in-depth review into Nvidia’s planned acquisition of the chip designer Arm from SoftBank, putting it at the forefront of what are expected to be a series of investigations around the world. Qualcomm is understood to be one of the companies complaining Arm could lose its “Switzerland” status if its rival Nvidia clinches the deal.

4. SoftBank’s OakNorth suffers defaultsOakNorth, the SoftBank-backed UK lender that once boasted of its perfect lending record, has incurred close to £100m in defaults largely as a result of soured loans to property developers. In Asia, the authorities are clamping down on digital lenders, stepping up to rein in a sector that has charged ahead with little oversight in credit-hungry large economies such as India and Indonesia.

5. Zynga walking tall with High Heels!Zynga made its name with FarmVille, played on Facebook on a PC, but its chief Frank Gibeau tells Patrick McGee it now aims to launch new cross-platform games that are able to be played across mobile devices and consoles together.

I was impressed with the incredible lightness of the LG gram laptop despite a 17in screen and 20-hour battery life when I tried it back in 2019. LG has just announced its 2021 gram range is now available in the UK and US. The five new models all have slim bezels, big 16:10 aspect ratio screens, rather than the usual 16:9, with the 17in priced at £1,399, 16in at £1,249 and 14in at £1,149. The keyboard and touchpad have been enlarged for easier typing and the 14in model weighs under 1kg and has a claimed battery life of 25.5 hours. There are also 2-in-1 versions with 360-degree hinges and a stylus, at 16in and 14in (£1,599 and £1,499), from March.
