You can earn 0.0002 BTC just by adding listings to directory.There is no limit here, so more you posting more you making.
You want business that accept bitcoins?
Isn't that obvious enough?

That's the whole point of the site: building a business directory with companies accepting bitcoins. Also take a look at the logo (spend-co-in - business drectory for the crypto world)

I have registered ... i ll' make a research for such business but here in Greece is difficult to find a lot, we are back in such development.
