50,000 USD will also be very hard for the situation right now. As long as mass of the 2018 adopters cannot get out in profit, new money will not flow in. Imaging of a case where many guys have alot of cash sitting in their bank accounts just to wait for any investment opportunity, but they have a friend that joined in 2018 ATH period and still deep in red...as long as this guy is still in red these "alot of cash" guys will not simply put in his money. You will need to see Bitcoin price go up above 20k and stay around that range for long enough to let those ATH buyers get out in profit, only then the hype can begin again.
