Probably like most people, I was very dubious about the whole concept of Bitcoins when they first arrived back in 2008/9.
As someone who started his working life receiving a weekly brown paper pay packet containing notes and coins, it is difficult to imagine a currency that only exists in Cyber-land.
Fortunes have been made and lost through Bitcoins and other Crypto currencies. Personally I would be very hesitant to invest, but I do know those who have, and they've done well.
Just recently El Salvador adopted Bitcoin as legal tender, alongside the US dollar. Otherwise Nigeria is the biggest user of the currency. Africa, Asia, and S America are also all big users, whereas N America, Europe, and Australia are hesitant.
With the predicted disappearance of 'cash', one can only imagine that Crypto currencies will play a big part in the future of both personal and national finance. Personally I shall try to pay with paper and metal for as long as possible. I do have a contactless debit card, but I'm very hesitant to use it.
When at The Nag's Head, how does one buy a Pint of Wallop with Bitcoins?
