Blaming the crypto winter.... great job!
The truth is that they started to die when they were forced to introduce KYC rules.
Since it was one of the reasons people traded there, they moved to another place
The same goes for localcrypto and a regulatory development that can take place when your company grow up.
It's called the
Darwin's theory. Only the best survives

This, guys. They blamed the crypto winter, economic outlook, etc., and yes, there's a truth to it. But the winter did not strike the first blow, it only slammed in the final nail.
Before they enforced strict KYC (they actually always had it, but it was either optional or very minimal, IIRC a phone number was enough to get by for most people), I would get trade offers almost as soon as I put mine live. Selling was over in minutes (literally, because of my location and mode of buying).
It was after KYC + the removal of face-to-face that they lost their niche. I took most of my trades off-site, so did most traders I knew. LBC simply became an additional listing site.
Survival of the fittest eh?
