Although you have already specified all the earning methods, there is another method I would like to add. Staking method, which is not a profitable method compared to other methods, but it is a good choice to create a guarantee income source and to obtain passive fixed income. On the other hand, since it is less risky than other methods, it does not create stress and is known as a method that does not make mistakes with bad psychology. In my opinion, the most profitable and most advantageous method will of course be the trading option. On the other hand, bounty campaigns can also be stated advantageously because they do not pose any financial risks.
