Hi, another newbie over here. That's what I'm doing for the exact same reason. BTC for me is a "don't-touch". So trying to do all my trades based on ETH and only buying new ETH from fiat.

It's not so easy, because most of the trading opportunities are based on BTC, but you also find some good ones. For newbs like us, we are the biggest limit actually, not the currency we choose as a base. At least, that's my point of view. Interested in other's opinion about this.
