Hi there nyerok! Yes I think to those people who start several years ago when the bitcoin price is below 1k. But to those people that invest a way more higher than 1k price, that is a total nightmare.
Theoretically, that could happen but in this day where there are so many traders and investor of bitcoin that can't absolutely happen. When the price of bitcoin will reach 5k or even higher, the traders will automatically buy as many as bitcoin that they could be. That will then result in a huge leap up to the price, and again when the price goes down again, those people will massively buy again. When that scenario is repeatedly done, there could be a long long month before it touches the 1k mark.
