Yes I would have to agree the ETH is really a good coin and it is even better than bitcoin, however, I doubt that it can grow similar to bitcoin because it is just another altcoin. If you look at the historical logs, it reaches ATH around May-June but haven't reached it again. While bitcoin is breaking ATH, ETH can't even touch $400 now. Although its on a current bullish run, but in the long run, it will experienced another dump causing the price to go to sub $200. So no, it will not grow like bitcoin, sad to say.
I am sorry, for me bitcoin is best coin. why?
While ,many might think that Ethereum may be inferior to Bitcoin because its price value is lower, this is actually a good thing for potential investors who are looking for means of investing other than Bitcoin. The lower price may attract more investors as there is more room for growth. The only drawback would be that Ethereum is not as well established as Bitcoin. In consideration of this, Bitcoin is safer than Ethereum.
