I try not to spend more than 1 hour of my day to bounties. The reason is: Even though I believe that cryptocurrencies have future and everything will be great again, we cannot be 100% sure about this. If the market stays in the bear season for more than 3-5 years, how are you planning to live your life? You don't have any other earnings and you will be depending on the money you are going to get from a project that you are not 100% sure about...
So, it depends, if you have money aside you can do it as a full-time job.
It is super boring though ...
