It's good to be cautious. I do not recommend investing too much and going into big rinks.
First we must invest in some Bitcoin. It will raise up suddenly this is great deal of increasing the money value. Past two years before bitcoin is 750 us dollar only. But now it is 5796 us dollar. This will approximately 600 percent increase the current market. So what ever happened in digital market. So we must invest and wait for the good deal.
