Is it better to save money in bank or invest it online, in real estate or maybe gold?

yes that's right, investing will make our finances well developed and investing in bitcoin is one of the best alternatives for now because bitcoin is capable of delivering very high profitability.

Investment means giving the money to someone who uses it for their business and pays you back a dividend (and you normally get some kind of share that can be sold later). Think stocks.

"Save in bank" is actually a kind of investment. You give money to the bank, they use it for their business and give you a small interest (if at all) as dividend, and you can withdraw your money. With current interest rates, this is pretty boring, the only advantage compared to keeping money in a safe at home is that it's easier to do most types of payment, and that you don't need your own safe...
For me its better to invest my money because i can see the result of my effort beside my money can use for invest for using business and i can earn more money...if i put in the bank my money nothing happen to my money except the law interest that the bank given to my money...but if i will invest it possible i can gain more money so its better to invest....

Buying precious metals is not an investment because those metals won't work with the money you paid for them. It's mostly speculation (you hope that you can sell it for a higher price) and safekeeping (real value of money can fall due to inflation, while precious metals will mostly retain their "real" value). But you need to consider storage fees.

To decide which is better you need to know what you consider "good".
Do you want to maximize your ROI? Do you want to store your wealth safely? Do you want to enable entrepreneurs to build their businesses?

I would rather invest than save if we invest a longer period of time than saving money. If we save not necessarily we get a big profit. In contrast to investment if we invest will definitely be profitable
