Bitter experience was not surprising. I began to be interested in crypto currency at the most favorable moment. After I bought bitcoin, the market grew significantly 
The bitter experience in bitcoin when the price goes down but I think it is normal to taste bitter in investment cause not all times are sweets. It is normal in all kinds of business have changed the value. Maybe at the moment you bought the value goes up and also we know that bitcoin is unpredictable but all investor's are continues believe in bitcoin no what the price is, bitter or sweet is not big deal for them.
