Those of you who already know and can differentiate between investing and trading should be willing to guide those who don't, not call them stupid. Because most people who trade by buying Bitcoin are still learning, and some of them still don't understand the difference between investing and trading, so they often think they're the same.
Many people are new to cryptocurrency and don't know much about investing or trading. Perhaps you seem to be new too and do not know or understand the difference between bitcoin and crypto hence when you want to talk about bitcoin like this thread is discussing about you should stick to the word bitcoin and not to sound vague using the world cryptocurrency which is generalizing in nature hence categorizing bitcoin with some kind of shitcoins.
Bitcoin is the anchor of this thread and when you want to refer to it you should call bitcoin bitcoin and not cryptocurrency, the thread says buy buy buy and sell sell sell which is (buying and selling of bitcoin only).
