I remember when I was looking at private anonymous coins I had the choice between DeepOnion, Spectre and NAV or TOKEN PAY ICO. I found out token pay was literally a rip off of Spectre. DeepOnion looked like literal money grab garbage with no actual usable technology behind it. I ended up putting my money into Spectre as it seemed like it was the only Anonymous Coin with actual developed protocol. DeepOnion seems like more marketing then actual development going on for me.
