Buying into Lisk at $7.12 is like buying into Bitcoin when Bitcoin was $52.68 and as you can see bitcoin has done x185 since then. Best case scenerio if Lisk would reach bitcoins current market cap $162,981,637,114 you would get x185 from your $7.12 buy-in. Assuming you invest $1,000 into lisk now, you get 140.44 Lisk tokens which if it reaches $162,981,637,114 market cap in one year each coin would be worth $1,317.20 , your $1,000 will become $185,000. Which is not bad at all, however we must assume this coin would even make it that far, it needs to find an audience that would actually pay that much for the coin. Looking at the big picture the coin could make it perhaps half way of that goal market cap which would mean your $1,000 turns into $92,500 instead.
