Is there a reason you do your analysis against USD instead of BTC? I've always done my trades vs BTC because I trade on 'trex (which I guess does have USDT, but then I would have to do a BTC->USDT exchange).
I think DASHUSD might be relevant on Kraken.
Can trade either denomination but USD value doesn't denote BTC value. So it depends on where one is trading and what the goal - accumulate USD or BTC.
I like both pairings personally and I think USD might be easier for some to visualize and learn TA from.
