Long-term investors are generally optimistic about the market and know that now is the best time to buy at low prices. The bear market is an inevitable cycle in the encryption market. Bitcoin still has strong market support, and the price will increase when it enters the bull market again.
Yes, and not only with respect to Bitcoin. I invest in the US stock market as well, and instead of thinking that it's a shame that it's gone down, what I do is take advantage of it to buy cheap. If the asset you buy is top quality, it always goes up in the long run. Times like this are good to buy on sale.
