After seeing this topic I was going to get any touch by any official person of Bountyhive through the bountyhive site. where I saw that:
Snip~~
I have already messaged colorlessk through telegram about this. If I will get an answer I will submit here. Thanks
Finally, I have got an
ansert answer from Colorlessk through telegram that they are not closing bountihive right now. But they do not want to add projects that they know won't succeed. So its really good news for bountihive user.

hope bountyhive will soon add quality projects again. indeed this year quite a lot of not-so-good projects were added to the bountyhive site. maybe they changed the telegram to avoid anger from the members who wrongly joined the project.
I have participated in several projects of bountyhive, and the results have been really satisfying. so I was calm enough to see this information, and hope that the bountyhive returns.
