As you know Bitcoin price shows that it follows a cyclic pattern so comparing it with the NASDAQ or some other stock is not good because of its own price history you can easily compare its current pattern to the previous one. Investors look to the previous history of bitcoin movements and then they predict the future price of it. Comparing it to the stock or other assets it's not familiar Besides this you can compare its current patterns to the previous one as bitcoin has a log price history. But one thing to be noted is that if someone predicts the future price of Bitcoin it does not mean that it will occur or follow the previous pattern 100%, bitcoin is volatile and its price can change from time to time so be careful when you are going to buy or do investment in it.
