I think it's due to the supply of bitcoins are lesser and the demands are higher, so the price will keep rising. As we all know, bitcoin is the first crypto to ever exist and it is also used for easy transactions in several countries. Bitcoin already served as the best crypto and it is popular to investors.
yep, when the supply of BTC is lesser, than the demand is higher, that's why the price is increasing.
i hope that the price keep rising and fly high
