Well, bitcoin is not money, but bitcoin is a digital coin as an investment opportunity that can make double the money even many times, but if bitcoin is not used well then it might not benefit at all.
Double the money? I mean there are a lot of times that Bitcoin made that possible but not all of the time. Being positive is not a bad thing but we should not always say that since most of the people thought that BTC can actually double your coin instantly not knowing how volatile it is and what are the risks in investing in this crypto currency.
