ETFs are safer because they have built in diversification. rather than putting your eggs in one basket you are investing in a whole range of companies and your investment will track whatever market the ETF is designed to track. If you invest in something like an S&P 500 ETF the return is something like 7-8% per year on average
Pod point is a single company that hasn’t yet made a profit. it’s not the only company doing EV chargers. It may turn out to be be a great investment, but that is not yet guaranteed. Established companies that have been profitable for a number of years are usually safer. So yes I would consider a company like Amazon to be safer. The chance of Amazon going bankrupt is negligible
