If someone is afraid to take risks in any business or business then you cannot do it.
Though I agree to some extent and I definitely agree that people should take reasonable risks, comparing the risks of buying bitcoin, a volatile asset, to starting a business is quite different. With a business, you have control with everything. If your business fails, you only have yourself(and your partner) to blame. With investing in cryptocurrencies though? There's only so much a single person can do to positively influence bitcoin's price, especially as a person that's not a sort of celebrity or "influencer" in the cryptocurrency space. Even as a celebrity or "influencer" though? It's definitely harder to pump prices right now compared to back then.
Therefore making your own business through bitcoin can also be an investment right? And can also mean that you will double the risk. It isn't really hard its just that people nowadays were just aware of the risk and more careful in putting up there money to this type of platform
