100 bucks, really?
Haha. I hope no one believed in the OP. Not saying it wont happen, but if it does, you are a looking a long time ahead in the future.
Anything can happen. I believe if the Ethereum is developed actively, the price will be over $100 in the next 5 years.
This could happen early if there are many Dapps based on Ethereum come out in the next few years.
