Abge - then inform me.
Your assertion that "bitcoins = cash" I get, if by "cash" you are referring to the general concept of money, with an arbitrary value.
If your assertion is that "bitcoins = US dollars" then you are wrong...but I don't think you are doing that.
so essentially, PE, in deriding me for not comprehending bitcoins, is right, and wrong. I may not understand the exact mechanism of bitcoins -- I admit as much.
I do, understand, that what the glorious youth are flocking to is smoke in a bottle. it's a gee-wiz, look at me cool gadget upon which someone has placed an (almost abitrary) value. I once used to be able to buy and sell Magic the Gathering cards, too....I'm not certain how lucrative that is anymore.
So fine...you have your e-coin, and it's unpenatrable unless I bonk you on the head, steal your wallet and computer, etc. It is still a toy, a gimick. My US dollar, in its myriad forms, is quite safe, it is quite diverse in the many forms in which I can use it, either in "hard currency" (which I generally shun), credit cards, various on-line mechanisms which all tie in to my central computer storage....which is ultimately protected by a government back/created value, and is protected from theft...even if someone bonks me on the head and steals my wallet...
Just because someone has created a gee-wiz, look at me cool new gadget that they say can be used as a better currency...doesn't necessarily mean it is. Not anywhere in the near future, that is.
