now a lot of investors are investing in bitcoin, therefore bitcoin has increased very rapidly if bitcoin decreased what should be done? whether the investors will lose? 
Investors will not lose if the investor does not sell Bitcoin at a low price. Unless the price falls again, the investor will sell Bitcoinnya, it is certain he will lose in large amounts. What we need to do if the price of Bitcoin decreases is just to calm down, not panic, not to sell its Bitcoin, and keep the Bitcoin we hold.Investor will not lose if not selling bitcoin in low price but many people sell their asset in low price because they are worry if the price even going lower.
Actually i dont hope this is happen but there are so many people with different opinion will make this market even worst.
