I bought bitcoin when it was around $14,500 in January and I am still holding because I am not discouraged. I have great hope that bitcoin is going to increase in price and volume in some years to come.
right, don't be discouraged, don't give in to losses. You have to be sure that bitcoin will increase again even though we don't know when it will happen, keep monitoring price developments, doing other jobs besides investing / trading, so you are not too stressful thinking about the price of bitcoin going down.
