Why some people want the Ethereum to over come Bitcoin in the near future? Is it because they make profit from ETH or what?
It's not necessarily that people want Ethereum to overtake Bitcoin. By looking at the technology Ethereum provides, it simply just has more features than bitcoin. Don't get me wrong i love bitcoin most, but the technology that Ethereum offers is so revolutionary that it is unlike any other (at least until every other coin out there copied it).
