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.
The problem is people invest in Bitcoin without knowing it's nature. People are not interested in learning things even when they plan to invest there. There is no guarantee that Bitcoin will be at a higher price than today after exactly six months. There is no specific time frame to cash out the profits from Bitcoin investment. They have to wait for a suitable time to cash out the profits.
Another problem is people think Bitcoin will always go up in price which is not true. It's volatile and this is the nature of Bitcoin. The stock market fluctuates as well. So, why blame Bitcoin only when there are similar things that are volatile as well?
