Obvious FBI is obvious.

A safe assumption, you can never be too paranoid. Make encryption for files and communication a habit, always use drops. Caveat Emptor. If you can't and have no interest in protecting yourself online, DarkNet is not the place to be. On the other-hand, if you take adequate steps to protecting yourself, you won't have much to worry about.
Dude, a tor-market place advertising publicly is obviously a
honeypot.
You, a noob profile talking about it is highly suspicious.
Rule number one : don't talk about tor-marketplace
Rule number two : don't talk about tor-marketplace
Rule number three : don't talk about tor-marketplace
