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? 
If the BTC decreased you have to hodl you coin and wIt for the price to get high it is good to buy at alow price then hoddl it for a high price if you sell, trade or encash it right away you will just earn small. Right now tge price of thr BTC is good it is increasing for me it is good ro buy now until the price is in 8k but if it reaches to 9k you can sell it but for me you hodl it first to make the price higher.
