I am a long investor of DeepOnion. I have had participated in the airdrop and earned a huge flow of money in that time.
However, I would not say it will perform same as Monero. Reaching $100 is far away. There's a lot of reason. DeepOnion is an airdrop coin, a lot of people have had huge amount of coins which is why the price is still $0.30, if you are thinking of long term holding like 2 years or more, I think within that period, $20- $50 is easy.
However, do your own research.
I have not read anything about deeponion for a while now, any interesting recent developments that made you think there will be a high demand for it?
Recently they have changed their codebase from bitcoin and litecoin which is a good update. Stealth address is enabled, DeepSend works has been stared as well.
You can also consider this Veil coin.
Veil is a scam project from some previous scammer. I can't give you the link right now because I can't remember where I had read the article.
