As long as it is indeed a project lol. Yes you can advertise bitcoin related projects, but remember you should post here
https://bitcointalk.org/index.php?board=84.0 if you are announcing a service, and this services board
https://bitcointalk.org/index.php?board=52.0 is supposed to be for people which offer their services and ad campaigns but people mix them together and post whatever they want.
As long as your project is in development phase, you should keep it here, when you launch the project and wanna try business then the two boards I linked will give you more exposure. I just hope it's not about monkeys and apes.🤣😉
