I LOL, I care mate, I have been engaged in this type of strategy for a while now since I started studying the movement of BTC, and I think it is lot more profitable when you sell at high and buy back at dip. You can do the calculation yourself.
It was actually a sarcasm to point out the stubborn nature of some traders who never sell at any point but keep on holding through bull runs.
I will build it higher than that before the next bull run, but I dont advise everyone to do that because it is lot riskier.
Obviously few people have actually been able to go through that cruise and end up with a profit but it is one of the best. I wont say its risky, but a logical one. Risk is there in any trading. But what you can also do is when prices seem to move in the same direction, try to make multiple buy/sells. Track one order to another opposite side order for the future. That way you would not be losing out on a certain market movement. But it can become frustrating to keep track of all the trades.
Those few people were the guys who had been able to own huge number of coins when the market price was the lowest. That was a kind of test market when no one or very low amount of people had belief in Bitcoin and knew that it is something that will pay off in future. Even right now, you can have some good amount of coins when the market is bearish again.
