Popular mangas ON THIS WEBSITE have like 2 or 3 scan teams releasing their version every week, yet I don't see any member of those teams coming complaining in the comments about some kind of unfair competition.
I understand that you were comfy being the only ones releasing this manhwa and you had (as we French say) "grass cut off right under your feet" (meaning you were overtaken, let's learn French expression haha) but like...? get over it??? Dudz, you can always release your version at your pace, you don't have to react like that. Why belittle the other team like that? Trashtalking them? And then trashtalking the readers too? People are happy to see more scans of the manhwa they like, it's normal. You're obviously not doing this for money so why does it looks like you're loosing hundreds of dollars each time the other team releases a chapter??? Why does it matter that bad? It's not a competition, if you believe you deliver a better work this shouldn't stop you from doing it. You shouldn't stop doing it just because someone is doing it too, you should still be doing it because you like the manhwa and releasing translations you made.
I've been reading scans online for years, it's the first time I see such an unnecessary drama. Maybe you should take a break, this is stressing you out wayyyy too much.
