nothing is guaranteed in life - but its not delusional to say that DeepOnion has the best requirements to be the top privacy coin.

Yeah, when additional privacy features will be implemented, it will be hard to stop from mass usage. But there is a lot of work for the devs, so wish them best luck and good mood ^^
Development and testing takes a long time, we have to be patient, remember that DeepOnion is not even a year old coin.
Look at Monero for example....they had real no volume/value in the first 3 years! 3!
