You must be kidding. $20-$100 by 2018 end? You mean AMP alone with the total supply of 1 billion would have the market share of at least 20 billion???
Now the price is <$0.3. In a year, you're saying it would ~ X 100??? Forget about the moon your rocket is straightway heading to Andromeda...lol
Well, x100 in crypto in a 1 year time span is possible. I know that last year in December I told a guy he was crazy for predicting Ethereum to go past $100. Look now, it already hit $500. These kind of gains are possible in crypto. But in order to achieve that, the project has to be able to finally build something really useful. There is a lot of competition: Steemit, BAT and now even IOTA:

Crypto has exponential growth and with BTC and soon ETH entering the stock market the whole crypto space will boom much faster than it already had.
