I remember an airdrop during my early year here in Bitcointalk. I remember it was named Community Coin where they airdropped coins which is equal to 1 BTC valuation to the member of this forum. Yeah, airdrop years back are worth participating while airdrop now is full of scams. The same goes with bounty programs. In 2017 and earlier, participating in bounty programs can give us a huge income. But now, those good days are almost gone. We can seldom see good airdrop since the majority of them are scams while bounty tends to lean on fixed allocation of rewards per week. But between the two, I will always choose bounty programs anytime.
