I heard CANN devs said 1 cann is backed by 1 gram CANN, this is just an excuse for pump.
And URO scam/shit also said 1 urocoin is worth for 1 kilo urea.
If I say 1 via is backed by 1 xcp, will those guys buy my via per 0.01 btc?

There will be (if there are no fails) also CocaineCoin in about 2 days. 13M coins = 13,000 kilos. You can change your coins for cocaine with the biggest drug lords in Colombia. Anyway... that thread is for VIA - not for pot dreamers.
