The social movement its growing at high speed, now in France too , see videos in youtube , search Tibu´s legacy (i think links are considered spam), its my traduction of Legado de Tibu in spanish , some in france called "L'eau ou un resto" (to the water or restaurant).
You can find information searching google for Tibu´s legacy, again im not going to link my website due to ethic.
I think i can´t afford a price of more than 1 BTC, im very poor on the bitcoin world. :-(, anyway there is a youtube video from Spain with more than 130.000 visits and growing .
Judging by the lack of responses here, I take it this isn't very popular in the bitcoin world yet (and to be honest, I wouldn't even have heard of it if not for this thread). Still, this seems to me to be little more than a modern incarnation of chain letters. And this also reminds me of another variant similar to this, that involved people drinking while making ever more outrageous alcohol related challenges to their friends, until a few people died.
In relation to the links, there shouldn't be any problem with posting them, especially since this is the Off-Topic section; at least, I don't think anybody else refrains from doing so.
