Only a fool who dont know the reason for his investment or what he/she is aiming at for investing in Bitcoin will feel discouraged because of a current slight movement which you called a dip. It's not always hard for you guys to call a slight retracement a dip, causing misconception, fear, panic and confusion to newbies who just started investing.
If you are an investor, and you still expect Bitcoin to continuously go up without any correction then you must be a newbie or someone who have little or not knowledge in Bitcoin not minding the number of years you have been investing.
Not only do those who do not know their investment goals get frustrated, but sometimes any market decline scares even experienced people. This is a natural human reaction due to the nature of the market.
Also, investors consider every small decline in the market as a decline. Because they know that Bitcoin never stays in the same place. A small decline in the market can be an opportunity for investors to make very big returns. The reason why it is called a decline is to take advantage of the opportunity to invest at a low price.
Therefore, investors call all small declines a decline.
