Is it better to save money in bank or invest it online, in real estate or maybe gold?
You never want to put all your money in one place, usually people invest 20-40% of their savings. Some invest more. But diversifying is the key to gaining reliable profit, because you will minimize the risks. So the answer is - both.
No estimates about it, i mean you can not say with certainty that 20% -40% is the percentage that is enough for us to invest, it all depends on the belief when we are sure we will dare to invest more than 40% of our savings.
