I have always preferred to invest my money. That's the only way to grow it. You can invest in other businesses, your own business, etc. Doesn't have to be bitcoin or one thing in particular. A diversified portfolio is usually best.
Yes, I agree. It's better to invest than to save money. By investing our money on something fruitful, we must expect that something will come to us in return of the investment that we made. Little by little, our investments will grow. Unlike on saving our money, yes it's good to save money. But if you aim to grow your money or to increase the amount of your money it's better to invest on something.
