If you are buying bitcoin with your discretionary income and plan to hodl for long there should not be any need getting scared to loss your money and also having concern about the price nature of bitcoin.
The case should be, but most people in the panic market, that is what affects their situation and way of thinking, the most dangerous risk of investment or trade in the ears by friends or people closest to, that's a fact that often occurs.
Example:
You bought Bitcoin today at $ 100k, you have a long speculation for your investment, but when the price of Bitcoin drops to $ 90k is held 1-2 weeks, That's when the whisper comes and you shake and panic, actually you already have your best speculation, but you panic and sell it, it often happens.
