tl;dr: 0.01 ETH for spam checking is a joke -
BEWARE OF THIS PROJECT
0.01 ETH is no spam check, it's money making, nothing else. So it isn't an Airdrop any longer, it's an ICO and a shady one, as it's nowhere stated how many coins are in the airdrop or if it's limited to a certain amount of participants.
Let's assume it's an airdrop with 3,000 participants, like most other airdrops these days.
That would amount to:
3,000 x 0.01 ETH = 30 ETH
30 ETH (at current rate) ~ 30 x 314$ = 9,420 $ or 1.55 BTC
1.55 BTC for 'spam checking' per drop...
But how many drops?
Let's see:
WOCO costs 0,00005 ETH on Etherdelta: 0.01 ETH >> 200 WOCO
That's what the airdrop needs to be in order to break even (if the price is stable).
200 x 3,000 = 600,000
Max Supply 50,000,000 x 95% that will be dropped = 47,500,000 WOCO
47,500,000 / 600,000 = 79
So it's a maximum of 79 drops
This would amount to 79 x 1.55 BTC = 122.45 BTC
Even if you change the valuation and give x10 per drop (2,000 WOCO), it would be still 12.245 BTC or 237 ETH...
