If you are expecting Cardano to grow 20 x, you will certaily probably agree with this statement:
Look at percentage difference in Circulating supply of similar currency(close competitor, say Neo). And reduce Neo price by same percentage. That's the price you can expect next year lol......
But, isn't it stupid coz how about the market size. Its growing market but won't be that big to support Cardano growth to lets say $6 ( Unless it becomes Samsung of Smart Contract's); especially when more advanced blockchains are entering in the scene!!!
Maths for Stupidity, lol
