In my years of experience with Bitcoin investment , I have never seen any rally in Bitcoin as we are withnessing today . Whales are no longer the only big fishes of cryptocurrency world ,but also top companies like MicroStrategy, Square Inc , Grayscale Inc , etc.
Presently , statistics has shown that more investors are holdl than trading and this will surely make the price of Bitcoin to increase more and more .
With respect to the price with which the price of Bitcoin will end by 2021 , I think it will be between $50k to $100k price . This is not to exaggerate , because there is still possible for a decline , but considering the present situation of things , am sure atleast , $50k rice value is achievable this year, and might go beyond it .
