With Bitcoin approaching $50,000, there is probably no reason why we should be afraid that it will still fall down below $20,000 within the year. Elon has jumped in the bandwagon. Microstrategy has been increasing its Bitcoin portfolio. Square has also converted a huge amount into Bitcoin. The Bank of New York Mellon, the oldest bank in the USA, has also joined Bitcoin. PayPal is also in the game already. There are more big news to come within the year and beyond.
Thus, my latest bet will probably give me some easy money.

Even though I bet no on this, there is still a possibility that Bitcoin will fall under $20k. We all know that the Bitcoin market is unpredictable. It is also known for its high volatility, manipulation, sudden surge, and sudden crash of the market. Aside from that 2021 is just at its 1st quarter so we have a long way before the year ends. So I think we shouldn't be complacent that the price won't fall below $20k. Anything is possible to happen in the Bitcoin market.
