I feel that "sad" is a poor choice of words. I want to see bitcoin growth and am not enthusiastic about its decline in price. I think it is important to remember though, that the price is still higher than what it was 6 months ago. Most people who are buying into bitcoin for the long run are not really looking that closely to the month swings. Bitcoin price is still up an exponential amount of what it was just a few years ago. I think it is important to remember this when reflecting upon short-term price swings.
I like it when I see newbies thinking like this, unless you are of course just a newbie on this forum and you have been investing for a long time, as it seems you are talking like an experienced investor. The truth is that downtrends are normal in any market, and rather than feeling sad for the market being down, what anyone should be feeling sad about now is not having money in fiat to buy more at this dip and accumulate for the future.
