Is it better to save money in bank or invest it online, in real estate or maybe gold?
For me all of the above. Save some money and invest the rest of it. I believe in this quote " Do not put all your egg in one basket"
Every one will follow the same rule but in some cases people might confuse about investing in different sectors. At the same time we have consider always invest with the profits you make from investment. If you don't follow these rules you will end up in loss.
Even you can follow your rules when you invest, it still does not mean investment can guaratee help you have profits forever. If your strategy, prediction are wrong, it really becomes meaningless when you look for profit.
I agree with you but you because of mistakes you can learn and this way you know for the next time what to not do to give you profit i would say mistakes are common in the bitcoin world and the popular one is panic selling.
