Just like all money then. What does the number of pounds showing in your online banking app actually mean? I mean obviously governments and central banks agree to underwrite currencies but the value of your account is still dependent on confidence and trust.
My take exactly, but, totally without any proof...
The topic of Crypto Currencies has been a topic on conversation in my small (6) group of similarly aged drinking Pals, due, totally to recent reports of scams.
To be fair, I think I would be right in saying that not one of us any real knowledge of the subject.
I don't think any of my little group have "dabbled".
Personally, it appears to be a solution, without a problem (rather like "what three words"). It is already possible to pay for goods and services online, anywhere in the world (PayPal, among others), and, to pay money to individuals, similarly. I just don't understand what "crypto currencies" bring to the party, other than the ability to speculate (which again, it is possible to do with money, and look how that has worked out!).
The only difference I can see, between Crypto Currencies and Money, is that the "value" of the tokens is being underwritten by some Organisation other than a State/Country. Whilst I accept that the promises of many States/Countries would not fill me with confidence, I am not sure that I would be any more confident in any Elon Musk type character, or "young entrepreneur" peddling his/her latest offering.
But, given that so may people (including some or my younger relatives) seem to be "dabbling", am I missing a trick here?
