A note of crypto caution

At the end of a week of crypto euphoria, with Coinbase’s successful IPO, Turkey has served a reminder that bitcoin can be put back in its box, with a ban on payments with cryptocurrencies.

On Friday, the central bank barred their use to purchase goods and services saying this posed “significant risks” and citing the lack of regulatory oversight, excessive volatility, the potential for use in illicit activities, theft of digital wallets and the irrevocable nature of transactions required.

The anonymous use of virtual money “may cause non-recoverable losses” and “undermine the confidence in methods and instruments used currently in payments”, a statement from the bank said. Turkey has the largest volume of cryptocurrency transactions in the Middle East.

As Elaine Moore cautions, investors in both bitcoin and Coinbase must reconcile themselves not only to the environmental damage caused by crypto miners, but also to the fact that states may act in this way and the US will never allow a digital currency to challenge the dollar.

There is also the risk of prices falling, but this was not on the minds of investors today as the crypto rally raged on through the “joke” token dogecoin. Alphaville reports it has risen more than 200 per cent in the past 24 hours and is 550 per cent higher than a week ago.

There seems no obvious reason for the surge other than another Elon Musk promotion of it on Twitter, and investors making sure they have the last laugh in a crazy week for crypto.

Tech tools — TCL’s Fold ‘n Roll phone

TCL’s Fold ‘n Roll smartphone/tablet

A slew of new smartphones appeared this week, although the most interesting unveiling was only a concept.

Amid the launch of a range of budget handsets, China’s TCL showed off the Fold ‘n Roll, which as Engadget described, ” starts off as a fairly conventional-looking smartphone with a 6.87in display, but it unfolds Mate X-style into a small, squarish tablet with a screen that measures 8.85in diagonal. Then, when the situation calls for it, that screen can roll out even further from its housing, bringing its final size to a full ten inches”.

Sony announced three Xperia additions: the 1 III, 5 III and 10 III, with the 1 and the 5 introducing “the world’s first Variable smartphone telephoto lens paired with a Dual-PD sensor and 4K HDR OLED 120Hz Refresh rate display”.

ZTE also emphasised photography with the Axon 30 Ultra, which launched in China on Thursday, with an international version coming in May. It’s equipped with three 64-megapixel cameras and an 8MP periscope zoom camera.

Finally, Xiaomi offshoot POCO had the UK launch today of its F3 flagship smartphone with 5G capabilities, as well as announcing the arrival here of the X3 Pro.
