I READ your letter from David Cairns with a sense of relief as my instinctive doubts about bitcoins were confirmed by his logical analysis (Letters, September 18). I have struggled to understand the underlying value of such a currency and it is reassuring to discover that there is none.
It reminds me of my confusion during the dotcom bubble as high-tech companies were created without clear business plans and yet soared in share price as investors piled in. At one stage I wondered if I had lost the plot and was hopelessly out of date with my understanding of business economics.
Unfortunately for those who did invest their cash in something they didn’t understand, the boom was followed by the inevitable crash.
Of course all currencies are only made viable by the confidence their users have in them, usually based on a government with tax-raising powers and sensible economic policies.
That is well within the reach of an independent Scotland, without the need for a fanciful and risky high-tech currency.

Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
Callum Baird, Editor of The National
