The problem about Ethereum is that scaling it is really difficult.
Not sure if these problems will be solved, the only thing I'm sure of is that if it fails, it would be 10x worse than the Bitconnect fiasco.
Yes, the actual problem is scaling not the price.
ETH can reach any price as it's divisible to lowest of decimals but it's the fees per transaction that's limiting it's rise.
If Ethereum works to solve this problem, ETH can easily win over BTC.
