You can of course wait, and Bitcoin will arrive at this price again on a certain day.
But you can still sell them now and buy them back at a lower price to avoid more losses, this is also a trading method.
If you believe this technology should not be so concerned about the price, just hold your coins.
Obviously, you don't really believe this technology because you are afraid.
Maybe it will, maybe it won't.
Perhaps one of the reasons that people are selling to cut their losses is because we've had an entire year of people predicting that bitcoin will massively increase in value before the end of June, before the end of July, before the end of August, and so on. These predictions have all been proved to be wrong. Why should anyone think that any of these predictions of bitcoin regaining value are likely to be reliable.
I and others who have said the same thing have been completely ignored. But, if you (meaning the bitcoin community) keep on making these predictions which are proved wrong time after time, then it's no wonder that large numbers of people are losing faith.
There were a lot of people who expected Bitcoin to moon again at the end of the year. As we get closer to the end of the year and it becomes more and more obvious that BTC isn't going to the moon, it's completely reasonable that people are losing faith and cutting their losses.
