It's not half-assing, it's a legit strategy. There are professional traders who have a leveraged (e.g. 5x) position open for months at a time, they start out with a bias, let's say LONG, and every time the price dips, they add to their position, a very small amount, maybe 2% of their portfolio. The price may go up, that's great, it's a little profit, but if the price goes down, they add more - maybe a 2.2% of their portfolio. This way, after many entries at a lower and lower price they reduce their "average buying price" so after a month they may have, let's say 50k USD worth of BTC at an average buy price of 75K. So anything above that price and they are in the green. When they start to think that the price is approaching the top, they start selling off bit by bit, because they know that they will never time the actual top, no one can, unless they're Nostradamus or something. Over time this results in an average selling price that is way higher than their average buying price. Repeat this for a year, you will be in the green no matter what.
