This is a hard call.  From a newbie perspective, I see BTC as being huge because it has recognition, "first-in" advantage, and is the "default" value everything else is measured against.  So naturally it has value, kind of like the "gold" standard.   However, I think the value is far too great for anyone new to the space to achieve great returns. So I think Ethereum is the place to be for new people to the market.
