How to tell "high" from "higher"? That is tricky bit. This strategy is fully dependent on the trend of BTC going up. If it would go down of longer period your strategy won't work.
Now this is a good question, how to define that traditional strategy. If you are a long term investor then buy low and sell high will definitely do you a favor, and also i tend to buy higher when the price breakout a psychological price, why not compounding when you are riding the trend?
you've never lost a trade using that "strategy" because you're in a BULL market
when Bitcoin matures and volatility will decrease you will most likely find it more difficult to make a profit..
And this is also the truth, since its the bull market and the price most likely will go up then any buy position will definitely make you some profit and its only depends on when. When will the bulls stops? Until then i think you better gain more experiences in handling the market. Cheers !!
