Bitcoin is a digital coin, I think there are many people who really understand digital money so that bitcoin is a bubble.
in this modern era besides the real world there is also a digital world and of course digital currencies also exist and bitcoin is a digital currency and king of digital money and if it is popular in the world I believe bitcoin is a universal coin that will be used worldwide in transactions digital.
the most complaints are bitcoin prices, but actually we can use them if we are smart in short-term investing.
