You are right but most of the people are looking for the positive side instead of negative side in order to maintain their trust in their assets especially to newbie investors who are not yet familiar on how the market works. But for the professional investors, they already know it but they were able to gasp to the situation and use it to their advantage.

I like your statement that "If there are no ups and downs in our life. It means we are dead ", yes you are right we can use this statement to compare to stocks and crypto assets but in crypto world it is not that solid yet in terms of it's foundation as it is still new compare to stocks therefore we need to market it in it's positive way and not the negative one so we can gather more investors that will push the market price upward steadily.
