Is the information from Twitter regarding Airdrop 2 related to the GFN price?
1 PHR = 10 GFN
It is not price of Graphene (GFN). 1:10 is the ratio of the airdrop. It means if you own and hold 1 Phore (PHR) in your Phore wallet at the snapshot time, you will be airdropped 10 Graphene and can claim it.
The price of Graphene will only be known when GFN is listed and traded on exchanges.
