I don't know why people say bitcoin is gambling. Its not gambling. You are investing your money and time. You use your internet. So its not gambling dealing with it.
Yes, I totally agree with you. Many people now invest in bitcoin as a gamble. They sell their homes and invest all their assets in bitcoins. I think people need to be rational to invest in bitcoins, do a risk assessment before investing, and invest the right amount of money to invest in bitcoins.
