At first, I entered the world of cryptocurrency with an "investment" mentality.
Soon after, I realized that it was more like a "speculation" game.
As time went on, I began to feel that it was more like a "gambling".
Later, I even began to wonder if there was a "scam" behind it.
Until recently, I felt as if I had been "robbed".
However, just today, a friend told me that my view was not far enough. In fact, what we did was more like making a "charitable donation".
