I do think that you should hold the bounty tokens that you will get from the bounty campaigns that you'll join. Of course, providing that you read the whitepaper and found the campaign worth it, otherwise, it would crash and you might gain nothing from it. Efforts will become wasted. That's why we need to choose the campaigns carefully.
Btw, you should work on your English man. Because, others might not understand you. Just my opinion.
