Nice work and info. I could add Sugarexchange and Oyster to this as my favorite ones at the moment.
I would like to see more reviews from you in future.
I invested in Sugar a month ago and nearly all of the money I invested is gone. Hopefully it returns, but I would be careful with Sugar. Oyster is a good product, but it's most likely the victim of one or more pump and dump groups. I would buy it at a low.
