Says it all in the subject

Which ICO would do X100-X1000 in 6-12 month?
Lets discuss the coins or ICOs of today that will grow the most in 6-12 month time...
Also lets discuss the category of the coins with the biggest demand and potential in the market (e.g. privacy-focused category of coins)
No one knows what the future holds, so your question is quite funny. And speaking of ICO, there's only a few with a small supply, so yeah, to predicting the price for the next 6-12 months is hard. Having said that, IOTA, Omisego is the best for me,
