Cryptocurrencies are surging again. Bitcoin has just hit an all-time high of more than US$72,000 (£56,300), pushing past the level of circa US$69,000 where it turned back during its last bull phase in late 2021.
Other top cryptocurrencies like ethereum and solana have reached their highest prices in three years, on the back of a run that has been going since the autumn.
The value of the whole cryptocurrency market has raced up to US$2.6 trillion, triple what it was worth at the beginning of 2023 and not far off its previous US$3 trillion peak.
Much of this run has occurred at a time when the US dollar has been strengthening against other currencies (though it has fallen in the past couple of weeks).
