What backs bitcoins ... the full faith and credit of what?

Capitalism. A bitcoin is worth what somebody else is willing to pay for it. Bitcoin's value is controlled by "the people". If "the people" lose faith, it loses value. I can live with that.

Considering there are more businesses adding bitcoin support every day, it appears collective confidence is growing rather than fading.

I'll concede that events may occur where that confidence may be shaken or collapse. I just think it is becoming less likely every day.

nope, regrettably is not capitalism .... I truly wish you luck. Newest invention in something known as the pyramid scheme. Many people were happy in pyramid schemes till they found out the truth. Then depressions came. I do wish you luck though.
