$BTC I will tell you a story, for example, the hardest thing to own in the market right now is gold, but this gold is very difficult to buy, and the total amount is limited. Will there be a group of people who first hype another coin and make everyone feel like it's time to switch to the leader? Then, they will start to offer more Bitcoin for sale and exchange it for a worthless coin. This coin will always give everyone a good expectation, but in fact, that expectation may never be met. However, it will definitely keep reaching for higher values. In this process, the BTC that is sold is what these people really want to possess. Well, take a closer look and understand it. Understanding this story may help you better understand the term 'currency' in cryptocurrency.
