I think it's great all of these vendors are jumping on the decentralized bandwagon and setting up shop on OpenBazaar. One thing that definitely concerns me, where are most of these vendors hosting their shops? For a normal buyer, running OB on Whonix with traffic routed through TOR seems sufficient. But Vendors leaving a TOR machine with their vendor shop running 24/7, effectively running a market in their home office, just seems like a bad idea. Hopefully most vendors are hosting their shops on VPS's in foreign countries.
If any vendor wants to chime in and maybe make me feel better about this, feel free.
you dont have to host a shop? shop is available if you are offline
