In the current economic environment, no investment can claim to double its capital. At present, you can't invest blindly, and you can't want to eat a fat man. Before investing, we should make a risk analysis. If we want to make a big profit, we will have a big risk. We should choose the investment project that suits us according to our own situation, and invest in several different kinds of projects. We don't put our eggs in one basket, so the risks are scattered and the benefits are balanced.
