i am a user on this site: bitsha**ing.com forum .... so im going to deal with a trusted seller on this site for 100$ and i also heard about this site as a scam site full of rippers and owner, admin, verified trusted sellers wont respond you after payment is done ..... so is this site trusted or not?
So you know the site is full of scammers: ..and you have to still ask this question: Sounds like you're just asking to be ripped off, no-one in their right mind would do business on a site like that.
No one in their right mind would post a thread asking if they should do business on a site like that.
Editing a bit. If a site has the reputation of having scammers then stay away from it even if you heard that there are some that are legitimate sellers. More often than not you'll get a scammer which could cost you money. So why gamble? Your question has the answer itself.
