Ironically, it is true that bitcoin will never reach $20 again! Albeit for the opposite reason the OP intended! Haha too true. We've all made bad predictions though. I remember mocking bears & saying we wouldn't go below 300 USD around January 2015. I ended up looking like an idiot. Hopefully things start to pick up soon because the current price is pretty depressing imo.
By december i think price will be around 600$, the financial crash of september is pretty predictable, alot of theories come out that support that.
If it hits then it will reach 600 or even more, who knows! But i`m confident that bitcoin is on the right path!
