There is nothing like risk. If you have to say it's risky, you'll lose everything. Just an investment. If you lose it, you can't get it back at all, and even you have to return part of it, which is very risky.
Stocks are risky and have daily limit. If you drop a few boards in a row, the transaction will basically be restricted and your money will not be completely gone.
In addition, the risk is also related to your investment philosophy and the information you have. If you find that the loss is irreparable, you must gamble with a glimmer of hope, which undoubtedly increases the risk; If you don't understand this industry, it is more risky to invest with a gambling mentality.
