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.
I would suggest to wait until bitcoin closes the gap down to $5000 before getting any bitcoin. It's hard to wait for the oppurtunity, but it will come and it will be a much better place to get in.
I think it will go to 5k before passing 10k. Be ready. set up your bank account links to your exchange and increase your limits wile you wait. when it goes to 5k go all in. YOu can bet the house on it.
