DeepOnion is certainly one to get into, and this is from a purely technical perspective. I felt this thread already had a spectacular showing by my co-advocates and wasn't going to beat a dead horse, but seeing a comment like this made me post because it's just so un-informed:
About Onion - don't be fooled. It's regular altcoin with tor on exit nodes. Nothing 'Privacy' here because every bitcoin wallet is supporting it.
DeepOnion actually works in the the exact opposite of the claim made here. The DeepOnion blockchain transactions all take place WITHIN the TOR network. There is no exit node traffic occurring.
