There are multiple websites that list hot live or upcoming airdrops
The best ones are airdropalert, coinarketcal, freecryptocoin, airdrops.io
Also search in twitter you can find a lot of airdrops there but beware of scams
Yes, but if we look at the percentage, there are not many successful airdrops even though the airdrop is on the website that you mentioned, even if there are very few successful rewards, this is what sometimes becomes a complaint of airdrop hunters, especially if the airdrop uses wallet ERC20, transaction fees when someone wants to sell it are clearly not in accordance with the reward they get.
