Agree pretty much with what Vangelo wrote above, but hey it is not the end of the world. Like always if we decline their offers they won't get any sales, that is how it works.. but unfortunately most people are living in oblivion and can't read in between the lines (not sure if they can even read the lines itself lol).. anyway folks, where I live at least I don't need to use any sort of electronic cash system, my day to day transactions are made in cash and I intend to keep that way for as long as possible.
Barter is an option for those who will refuse the new financial system that will settle down soon. I know quite a few people in the country bartering all sort of things. As always there will be some alternative, by the way, if money was dead today, I would jump straight into Monero NOT Bitcoin (highly compromised).
