I guess it was much more a coincidence. The price is based on etherdelta prices https://etherdelta.com/#POW-ETH which bases on sell only from those who received some coins in the blockchain with that marketing campain. The thing is: the airdrop is linked with you FB account and each token will be swapped to a real ERC20 token by the end of the year and then, and only then, you'll be able to exchange it for anything.
Look at their whitepaper: http://powtoken.com/POW_Whitepaper_19_09_2017.pdf . Based on their previsions, this could really worth some good money. The amount of coins being distributed is still very high. Even though its valued as eg US$0.001 would still give you 300bucks from the void! And this is definitely an achievable price! There are 240billion tokens out there and eg Bytecoin already passed that mark with 183billion coins.
This is an airdrop, like all the others spread along BTT, with a different approach and still open! That's free money, no matter anyone say the opposite... you can register yourself and wait holding your popcorn until it sees the sun ... or just don't and may lose the chance of winning some. It's up to you guys! My slice is already guaranteed
