It is an indisputable fact that investments in securities are safer than cryptocurrencies. All companies whose shares are listed on the stock exchange are required to publish financial statements and undergo audits. And the fact that they are legally regulated allows an investor to receive compensation in the event of bankruptcy of such a company.
Actually, all investments carry the risks. And to calculate how much risk there is in any investment, the only thing you need to pay attention to is the price volatility of that investment source, because I personally think that the higher the volatility of an item, the higher its investment risk score. Although here, along with the risk, the potential for profit is also very high.
And here I would agree with you that crypto currencies are a little riskier because the volatility of the coins here is lower than many shares in the stock market and although the potential for profit is lower, the amount is higher.
