I think you should better work on usual job or crypto related job and invest money in crypto. But don't do bounties on regular basis. It is not stable income and you will waste your time
do anything that can be profitable, and choose a field that you can afford.
Crypto is a tool that can make money and if you can do it well maybe you wait to get the results that are worth it.
prizes may produce but they will not always get money so you say it is just a waste, it doesn't have to be and depends.
