If you save your money then it's amount will remain the same.
But in case of investing it, you can increase the money, may be many folds.
Higher the risk and higher the return.
no it won't remain the same you will actually lose money if you save and nothign else, because the inflationary nature of fiat(i'm assuming that you will leave your wealth in fiat form) will be agianst the purchase power of your money, in the end you will buy less thing
this is also happen very fast in 3-5 years, because if i'm not mistaken the the average inflation is around 8% per year for fiat currency
True, and not only that but the salaries are going lower and lower. So if you are a wageslave like most of us are, it's guaranteed the purchasing power goes down. If you are an entrepreneur, people has less purchasing power = has less motivation to buy your products and services. It's all a chain of never ending poverty. Lucky we have alternatives to save our wealth now like BTC.
