That dude was definately very lucky. but best thing was that he was prety sure that Jupitar will give airdrop that's why he spend so much time and resource on that. which finnally paid off and he ended up getting $1 million.
i hope he use those money well and not loose them in scam and stay safe from hackers. because hackers will be targeting him now with full force.

Only luck won't make you eligible for airdrops, You need to believe in projects too. if you work more and contribute higher in certain projects the chances of earning higher airdrop will increase gradually.
