Have you thought about trading on 2-4-6-12 hour systems? 2h system is interesting, a lot less sideline trades, but still decent amount of trades.
That definitely is a valid approach. For me, it's a time commitment thing as well...BTC isn't the primary market I trade, so I really need to spend the majority of my research and screen time elsewhere. By trading the daily timeframe, I'm allowed to still focus on my primary trading while being exposed to the major price swings of BTC.
