The cryptospace has a lot of opportunities to offer to whoever is ready to benefit from it. There are airdrops that you can earn from by completing some task and get rewarded with their airdrop token but personally, I believe that investing in bitcoin and hodli is a better opportunity one should take advantage of so that in future you will benefit from your bitcoin investment when the price of bitcoin would have skyrocket to an unexpected price. Trading is complex but if you can take your time to learn and improve your skills, it can be profitable.
And besides, airdrops campaigns there are other opportunities to earn, you can also trade Bitcoin, altcoins. There is also opportunity on staking/saving crypto coins to earn passive income everyday.
Now, airdrops payment this days are not encouraging, I think trading is better, though it requires some experience to winning trades regularly.
Staking/savings is a great option to earn, it only need patience, but flexible savings can be another earning option for persons who can't wait for a long time.
Finally, bounty is another great options, it always requires dedication, and consistency to be on the forums especially Altcoinstalks and Bitcointalks.
