Why was an ID number 4 added to the lucky conditions in this airdrop of $boop?

Does everyone still remember CZ's gesture for '4'? This wave seems to echo that, anyone whose last digit is 4 has hit the lucky number sent by CZ to the community!

Binance knows how to play this game! I'm also quite lucky, my last digit is a 4, haha, by the way, don't forget to maintain a certain point requirement, this is always a basic condition!
