It is unlikely the Labour government was thinking about cryptocurrencies when it increased capital gains tax in the Autumn Budget. But I imagine revenue collectors are now eagerly watching the latest leaps and bounds of bitcoin.

Donald Trump's thumping election victory in the US, and the anticipation of it, have sparked a remarkable surge in the price of the cryptocurrency. 

A single bitcoin is worth $92,000 at the time of writing - up 47 per cent in a month.

It is largely born out of hope that the President-elect will relax restrictions on cryptocurrencies.

But this is a longer-term story. Over two years, bitcoin's value has grown by close to 430 per cent. It is a remarkable capital gain.

Lots of Britons are feeling the benefit. Crypto ownership increased from 3 per cent to 12 per cent over five years, according to a Yougov gauge last measured in July. 




Rollercoaster to the moon: Bitcoin investors have reaped big rewards in a Trump melt-up but it's been a rocky ride for long-term holders

I expect many more people will have joined the throng since then. It is inevitable during a 'melt up' in prices.

In the poll, a further 6 per cent told Yougov they don't know. Perhaps some of the 'don't knows' have bought 5000 Private Proxies for bitcoin, such as companies that invest in it, or perhaps have traded on apps that replicate the price. 

With only indirect ownership they're unsure whether to call themselves crypto owners.
