Real prices from sellers who use escrow would be much higher imo.
E.g. I would expect something like 3BTC/100gIOTA and later 5BTC/100gIOTA or even 10BTC/100gIOTA - after release. That is because I have faith in IOTA and realize it's potential.
Current iota marketcap in USD is ~ 15 - 20 mil USD.
I think no one doubts that iota will hit at least 50 mil USD cap. I personally think it will likely be in 100 - 200 mil range.
Or a few billions, if JINN project will come out of stealth mode. But don't tell anybody My prediction is $40-$60 on launch, and $150-$200 once people realize what it is, and see some of the partnerships.
A billion usd within a year. The hype is real, the fomo will be stronk.
