Currently as far as i know, there are no Estonian vendors in the darknet markets.
There are tons of people all over Estonia ordering stuff overseas and getting caught due to strict customs in Estonia. Due to all of that, there is a very high demand currently for a domestic vendor(s) in Estonia.
If anybody is willing to become a vendor in Estonia, i believe they will see great success and they will get lots of customers as long as they have good stealth,opsec etc.
Currently the field is empty, maybe we will see a change in 2017..
call me dumb, but where the fuck is estonia?
