The biggest money making slot in crypto space is to be
1. a developer
2. build crypto wallets for new projects
3. find bugs in the system of many new projects
yes some paid for security breaching and all that stuff, rendering professional services is the best way to make money in crypto space now
You can't be more accurate than your statements. However, one don't become a developer simply by tweeting, posting videos, and writing articles in the forums. It takes a life-long learning to get there. CZ that built Binance didn't just wake up and built the Multi-Billion dollars crypto exchange - He's been a programmer all his life.
Many who are into bounty would want to become successful developers and make a lot of money, but they just can't afford it yet and must do something else to sustain themselves and their families.
Of course, you should not also forget that the services of bounty hunters are also very valuable in the crypto space, as many new projects rely on their involvement for the projects to gain exposure and attract investments.
I think they should not forget bounties and airdrops as long as they're making a living doing those. And those of them who can afford to learn coding and become developers should be encouraged to pursue it. But one thing is sure, not everybody will become developers and hackers. There must still be those that will do the marketing and sales jobs.
