yes, I think there are many people who think like that. and I'm sure, many people are engaged in the field of crypto just to get big profits. I even think of building a business that accepts payments with cryptocurrency.
Actually only a few knew about crypto currency against the total population but is increasing directly proportional to the bitcoin value. Crypto currency is now functional and regularly circulating in the other business transaction. Crypto currency is officially used and I guess this will be the future. Considering its value today its worth to invest and start making money.
