1000,000 USD ? or you have put few zero extras while predicting the price of bitcoin in 2020.
Believe me you will lose your bet. That's all i can say about your bet.
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.
Even 50,000 USD bitcoin price is hard to achieve this year. If you want a safe bet you can bet that bitcoin will reach 20,000$ by the end of this year. This will be very much possible because bitcoin prices reaches the all time high after every halving and it can continue to do so this year also.
20K too wouldnt be a bad bet if one were to just buy and keep for one year from the current point. What factors you think will push the price to 20k? Some say halving some say adoption by new users...
