They are currently holding their sig campaign in the forum so I think that's one way of their marketing campaigns.
And have you noticed, their price increased just before the airdrop and now, it is sustaining the 900+sats level.

They are running two promotions: one with signature campaign, and one with Twitter. They increase their exposure to eyes of crypto investors. Airdrops can be some of reasons people buy PHORE and it help the price grows up. I am happy and also surprise that the price does not fall after the first snapshot.
And now, in this upcoming second airdrop, it may further increase its value.
Maybe this coin is worth investing at. But check first their graphene project potential.
It can cause another new capital from investors to hold Phore and take airdrop for Graphene. With the hype in DeFi, I think a price at 1 dollar is very possible for Phore. A first target of its rally and it is the nearest resistance on the chart too.
