The article you have mentioned gave a fact about bounties and airdrops that they are no longer good in these times. And as for your question how you can increase your income, learn something new. You can upgrade yourself in trading or get an additional skill that you can work with or start with a business that you can operate despite the situation.
yeah . blaming cant help us solve this problem but instead it can only make the situation worst because you cant do anything productive if your mind is foccusing on someone else . anyway its hard to start a business now because most business are not allowed . online business can be good as alternative anyway . still its hard to cash in on some places because like i said earlier , many establishment or business are still close . people need to start from scratch and find way to produce free money online to be able to get started with trading and other real profitable acts aside from bounties/airdrops
