You can find some good airdrops on Airdrops.io website. Some exchanges also pay to join them with their own coins (IDEX currently has an offer of free IDEX coin if u make one trade before March). I am also mining on my mobile phone which is free and simple for new coins which may be worth something in the future. If you are interested to check them out they are available on Google Apps and they have good ratings by users, Pi Network: which has 13m users and is 2 years established, you will need an active referral code to sign up so you can use mine if u want and u will get one free Pi to start with (referral code = syedm786). The other is Bee Network, this is fairly new and similar, has around 4m users and only a couple of months old which means u will get a higher rate of coins (referral code = syedm1). They seem legit projects but best u check them out and make your own decision (you don't have to do KYC at this stage, just need a mobile number and referral code). You also need to log in once a day to mine the coins. If u want to use a different referral code it's fine but make sure it's fully active or could slow your mining.
