He does not know much about crypto and he's not risky, that's understandable. When you learn about crypto, you will see the benefits it brings to decide whether to risk or not
When you decide to invest in crypto, you only have two choices: your money will increase or disappear. Because price movements are very fast, from red to green or from green to red. The element of speculation is bigger than the bank. If your money is held in a bank, the profits are small, but your money will never be lost. In my opinion, the safest way, half is stored in the crypto money and half is stored in the bank.
