If you look carefully, you will realize that we are mostly promoting crypto projects freely! Like you are promoting 20 bounties but you only receive payment from 5 projects. That's mean we promoted those 15 projects freely, right?
Nobody wants to work for free. But is the situation as easy as you said? I do not think so. Sometimes it is difficult to find a solution, even the bounty you trust may scam you. You can accomplish something if you act together. For example, create a group in telegram and share your ideas. Choose the most suitable one and join it.
the fact that we will not want to do work without pay, but in this industry projects pay only with tokens they create and several other projects pay with bitcoin but the amount is very small for projects that pay with bitcoin. so the situation is difficult and sometimes we are also deceived because of misplaced promotion, and indeed we must accept this after choosing at the beginning.
But for me personally, for now there will be many people who choose to promote a project that dares to pay with bitcoin because we know that many people today are starting to lose trust with new projects that make payments with their tokens because most have failed and some tokens which is obtained in the end has no value and only becomes junk in the wallet.
