No, The supply of Ethereum is very large to be able to reach the price that Bitcoin can reach, it's not even close. But those who say that there is no altcoin that can compete with Bitcoin in future is totally wrong, there are lots of altcoin that has the potential to grow like Bitcoin in the future, but the thing is Bitcoin being the first cryptocurrency that had been introduce is making it more popular than other cryptocurrencies and also one of the reason why it remains on top and that gives those altcoins a hard time to catch up. I think Litecoin, Dash, and Monero have the higher chance to compete with Bitcoin in the future (if the scaling issue is not yet solve). Don't hate me, I may be right or wrong.
