Probably they would put a mechanism in the system to just buy gzr with fiat for this kind of things.
You can't expect a player abandon his game buy some gzr from exchange and send it to hiss gzr account
Boost can't be converted into GZR, but we're working on a few different ways to facilitate the in app purchasing of GZR, being a company based in the USA, we are extremely diligent with compliance and are exploring different options. Early adopters will send GZR from the presale and the sale can link their wallets to their GGID, they will be able to send GZR to a smart contract which will result in the unlocking of an item based on the pseudorandom encryption hash of the token that can be equipped to a users avatar. There are several strong options for us to increase mass adoption and a create a seamless user friendly experience and a lot of cool partnerships and integrations which can use to exchange GZR on Gizer; our team will talk about some of these options in our Medium blog post.This is a great issue to talk about, thank you for bringing it up!
So you are based in America, then probably you will give permission to U.S citizens to join.
Did you get permits for it? Or will you apply?
I know it is very hard to get a permit for it. But make U.S citizens join is always a good force behind all icos.
