I have just read what you have written 3 times and I thus presume it is my advance years that are precluding me from understanding what it is about. I just cannot follow what you have stated but I appreciate you taking the time to do so,
My earlier visit to the Wikipedia page didn't help either.
I ask again: is it all a con?
Are there loads of people making a lot of money out there, somewhere, having taken advantage of the gullibility of others?
I can see money in my bank account but, if the relevant computer systems crash out there in the cyber world, what proof do people have that they had the bitcoins?
If I have a Â£10 banknote, the governor of the issuing bank promises to pay me (the bearer) the designated Â£10. If I have a bitcoin out there wherever "there" is, I can't walk into Tescos and buy my groceries with it and get change.
Maybe I was just born too early for this sort of thing !
