Investors are always looking for the safest investment even though it has risks, because there are also investments with less risk so that can be a special consideration for those who want to invest. For example, for investing in digital currencies like Bitcoin, even though falling prices are part of the risk, the upside and recovery potential is also never lost on assets like Bitcoin.
Likewise with some other real assets that may be less risky and those who choose it can benefit more when they have owned it for years, for example, such as land and housing. I think after understanding how the risks are, everyone can definitely make their own choices in terms of investment.
Safest risky investments? What the hell are you speaking about? I fully disagree with you - Bitcoin is the less risky investment for me as it's #1 cryptocurrency and it will rise again for sure. What concerns other coins, I'm not sure that they won't disappear the next day as most of them don't improve anyhow.
