I think deeponion has a chance of good success, only few real competitors that I see is Zcash and Zencash. Monero and byteball are quite traceable there are 30% tractability possibility that devs of Monero confirmed themselves. zk-snarks are untracable as of yet, will see with Deep onion, but idea and team are good so should go quite high as a coin.
I think deeponion coin will be success by strength of community
That's right, there seems to be a very big community forming around DeepOnion, probably mostly thanks to the well-done airdrop mixed with signature campaign over 40 weeks. And coins with such big community support tend to be much more successful. Also the native TOR integration gives it added value, so I'm also positive about it.
