Bonds offer decent investment opportunities, but they are not risk free and are quite expensive at the moment due to the high interest rates. High inflation usually means high interest rates at the same time and let's investors look for new investment opportunities to get better returns. Investing in corporate bonds offers the highest returns, especially the junk debt pays high coupons, but they also have the highest chance of defaults and losing our money.
I don't think people get poor from saving money, they might not become rich, but at least they shouldn't be worse off. For me saving is the first step of taking money out of my monthly income and protect it from not spending it during the month. Once the money is out of my main bank account that I use to pay bills and any other purchases, I will look where to invest that money. Some form of cash like saving is important so can cover any emergency. In case all our money is invested we could be forced to sell at unfavorable prices to cover our financial needs. Crypto currencies are a great form of investment that should be part of any portfolio. Taking profits in a portfolio is fine too, the question is then what will we do with the money. Investing is definitely the best option for what we can do with our money, it's going to lead to the highest long term returns. The issue with invested money is that short term price fluctuations can send the price down and lead to loss if we are forced to sell. Which is why I think that everybody should have at least some savings to cover emergencies to not be forced to sell at unfavorable times.
