I currently have my interest in airdrop and bounties but the truth remains that the payment rate for bounties and airdrop is reducing, blockchain holds great promise and I feel it's necessary that one start taking courses on programming, because i see Blockchain technology becoming a major additives for applications, its never too late to stay relevant.
And it will take you years to learn programming, and it will take more time to have enough knowledge about blockchain and project development. I think that is a really bad strategy, it is better to continue participating in bounty and airdrop. There are still many good campaigns and if you work hard, I believe you will still get money from it
