Yes, I totally agree with you. Whenever you choose to invest in something, you must accept that it always include pros and cons. You can make a profit with it, you also can loss everything in a second. It is basic knowledge that you need to know about risky investment. You may be failed, you may be lost everything but should never regret about your investment, because it is exactly what you want at that time. However, I also think that you should prepare enough knowledge about your investment for yourself before investing. That would help you limit the loss.
