Fundraising is very slow, most likely the project is not very interested in investors. It is very urgent to do marketing so that more people are attracted to the project.
I have seen a lot of projects paused in the middle of crowdfunding because they are not getting enough investors to invest, it is expected at this point in time where there are a lot of scam projects, it's still best to do a campaign for private investors before going to public, so even if you did not reach enough funding in public, you still have your private investors to back you up.
