What well known companies are planning on accepting them? I think it'll only take one big company to start using them and the value will skyrocket again.
Just keep browsing the press section, theres at least 1 biggish outfit announced per week that accepts them...
Keep in mind, some arent in the states..
Also, the numbers of places on coinmap.org grows , almost at 2000 worldwide, granted these arent big companies ... but still, it shows adoption =)
