Holiday Airdrop? thats cool. But let's accept the reality it's not easy to give free money nowadays because we are in the middle of a pandemic.
By the way, there are some platforms that always promoting some Airdrop and Bounties but you should put in mind that there is no guarantee in that said method and consider it as a gamble because you will invest your time and effort to complete those task. 

Another option is joining some giveaways like the CoinMarketCap Bitcoin price prediction contest who knows you will be lucky enough to win that $2K worth of BTC if you exactly guess what time and day Bitcoin will hit the $20K price level.
