Do you hold cash in bank account or invest with high inflation and a volatile stock market?

Hello, I am new to investing. Inflation is about 6.5 to 7 percent in US right now. Stocks have been shaky to start this year. I have some money invested in stocks but I keep the rest in a bank account with a very low interest rate. Keeping cash in the bank account will reduce its value while gaining very little interest, but I am nervous about stock prices crashing.
