In my own personal opinion, there are no such thing is the best time for promoting projects because anytime is the best time to promote a project, as long you are appropriately and uniquely promoting your project to attract and invite investors,
I do agree, there is no such thing as altcoin season. Anytime and any moment, bounty projects can successfully launch.
It is just actually a stroke of pure luck if you participated in a successful project.
but for now it is not the best time to promote projects because most investors have stop participating in projects due to scams.
Yes, bounty campaigns nowadays are not profitable, most of the projects are not even able to raise enough money to fund the project. Most of them did not succeed nor becoming a scam.
