There are many possibilities dude. The crypto market is highly volatile. You never know what may happen here the very next minute. This $50k prediction seems to me quite unrealistic as of now, but can't say anything for you never know what happens till the year end!!
And yes that's right, there is nothing to worry about for the long term investors in this market because sooner or later they will gain a very handsome amount from here. Moreover, long term investment is not an option with everyone of us here. Majority of people here are either day traders or short term investors and their state of mind right now is quite perplexed, that whether to hodl or sell!!
Many richest people in the world are investing in Bitcoin now. Recently, Rockefeller Foundations decided to buy BTC and deal with the cryptocurrency. All these signs signal that it will grow but probably it will not reach 50K this year.
