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.
