Totally agree, all trading, investing, and gambling will not be separated from the name of the risk. because all of these systems use a profit and one lose, it's been the law of investments, gambling, and trading.

Obviously, someone should only dare to invest if he can take the risk because at the end of the day it is your luck that will generate a lot of profits for you from your investment and if you get unlucky your investment can be wasted in any way.
