I can't find any reason to blame bitcoin and if you unknowingly buy bitcoin and then lose it's never bitcoin's fault. You should know that there are many big investors in bitcoin and it's price is not stable so catching the dip price at the right time will be profitable. You should keep money separately for family living and with extra money you can start any other type of business and it can be crypto. No one will expand the business because there will be risk for any business! This is an accusation of unethical behavior so in crypto you can buy token but definitely review with experience.
