I have been searching income from internet in the last 7 years. I have done many works like-PTC (paid to click), revshares, data entry, micro earnings, Upwork, and finally entered into crypto with bounty hunting and trade. Actually airdrop wastes time and internet MB. I won't recommend airdrops except few ones. Bounty is the best earning way from crypto world. Trade is also a better earning way but it needs capital, time, analysis and money management.
