I find this survey as a joke... made with only 322 individuals from 130M people that Japan have.

Let's also look at the REAL Bitcoin adoption: merchants

Even Spain + Portugal (that are shit in the adoption matter) have double number of merchants. Not talking about the whole Europe.

US is a shame LOL, for big it is I can count less than 1000 merchants ! You guys have big work to do there, stop using those shitty VISA cards and USD. Is time to make an example to the world.
