Luna2 airdrop requirements?

Maybe it's a silly question, but in order to take the luna2 airdrop i must have held my previously purchased luna, since the snapshot?

I have some questions :

1) I took 60 luna2 for 2.5m luna held on binance at low price of 0.000015 or lower. One time i had 25m luna. That mean that i would have taken 600luna2 airdrop? And all this for 150$ purchase? This is unfair for pre attack holders and very lucky for gamblers like me.

2) I bought at coinex 250 luna at 2$ price for 500$. Some time my 500$ went down to 5$ and i sold them to buy something else. So i get no airdrop there?
