You are allowed to bump your own thread no more frequently than once per day. You should remove old bumps as you make new bumps.
See this
rule:
4. Bumps are limited to once per day (24 hours), yes this includes "updates", that's what the edit button is for. Old bumps should be deleted as they serve no purpose, and only clutter up topics and make it more annoying to read.
There are also special ways you can bump a thread in
certain sections:
- Service Announcements
- Announcements (Altcoins)
- Tokens (Altcoins)
- Bounties (Altcoins)
