For me, why people are still buying bitcoin because of the main reason, they can still profit from it, and they want to use it because of bitcoin’s capability. Many people or users purchase bitcoin because they can even earn money on it if you can profit a massive amount of money even bitcoin’s value is fluctuating too much why you will stop. The over factors is there are grabbing this opportunity to buy bitcoin at a low amount and sell it to their effective rate. The last reason is maybe they want to use bitcoin we all know that bitcoin’s acceptance in big, in terms of payment system, because most of the establishment now know about bitcoin and some of them accept bitcoin as a payment, less transaction, and hard work to some users if they are using bitcoin, like no more queue.
