There are more and more garbage rewards, but a rewards project often takes a lot of time, this is the contradiction, so the best way is how to choose quality bounty, always observe the progress of the project, if the project is not going well, then there is a high probability If you fail, the bounty will be worthless.
Participation in subscription companies, I do not think this is a waste of time. Sometimes we get coins that cost very little. This is a risk.
