Pls suggest me legitimate airdrop and giveaway or where i can find list of airdrop.
Have you ever joined the telegram group specifically talk or inform about the airdrop? In some social media, there are also so many airdrop lists that are informed by the members.
I am looking for airdrop that listed in exchange....
Well, it is actually quite hard to find this one moreover the legit one. But, you may find some. You may check Origin Protocol Reward monthly that is commonly done by different tasks every month. This has been listed on Binance and this project is good enough. Try to find OGN there.
