Lots of Exchanges, Wallets and Trading services, but there are also some interesting new Applications that are emerging.

@sidazhang - true that the interesting categories are the ones with fewer players in them (emerging). what do you think is going to happen to the Wallets space? So many players there!

@wmougayar - your blog post mentions the ability to follow and receive weekly updates to the database, but I'm having trouble finding that feature.

Great collection. Very impressed by the work you have done

This is great! Where are you finding the companies?

Good to see Bitcoin on PH.

This is pretty awesome. Can get a pretty good sense of a broad pictures of what people are trying to do with crypto-currency. There is the usual suspect of wallet/exchanges etc. But there are a lot of projects also trying to use Bitcoin in a more meta way. Like doc verification, proof of existence type projects, embedding data etc

Good idea, how to get into your list? :)
