well people still does not know much about bitcoin here there is no real activity , and i can tell you that is a very sad thing , because here we have a big problem encountred mostly by young people who wants to work or trade on the internet is that our local currency is not convertible to dollar or euro or any other foreign currency , even paypal etc does not . people have been asking the gouvernement for years to change that . and saying so bitcoin would be a well fit solution for this problem if people were aware of this
If it is hard to convert, you can always look at goods that can be delivered to you.
There are a lot of Bitcoin merchants, you can start with the Marketplace subforums here (

You can get physical goods delivered to you, or digital goods if getting deliveries to Tunisia is hard.
Above all, welcome to BTCT!
