Credit to @nour for bringing it up.

List of my changes:
- remove Volume multiplier
- remove donator multiplier
- fix date to 19th
Explanation:
First of all I think people should generally be rewarded no matter their Volume. We should remove the Volume multiplier, because its only playing into whale hands and discourages smaller users.
If they used the platform TWICE give them their airdrop.
Why twice? Because we can filter out many bots with raising it to 2 tx. (Nour already included that in his post but I wanted to add why I personally think this is a good addition to the past dydx drop)
I would even remove the donators multiplier. People should donate because they want to support the project not because they want something in return.
For the date I would simply choose everything before 20th. Until the 20th, everything was speculation, so making the cut before the announcement of today makes the most sense without cutting off active or new users.
Feel free to discuss below and put in more Ideas for Zigzag to decide on the future airdrop.
Happy trading :)
