It was obvious to buy Bitcoin at the dip after it bounced off of $20k. Shills were paid to astroturf for Bitcoin, leading up to the rise, but were then paid to shill against it on the dip. I sold at over $19k due the pump and dump being revealed merely by the amount of shilling. I bought back in again, when they abandoned the scene. I anticipate the same thing will happen again, but I get OPs frustration because a bunch of assholes were running around saying Bitcoin is stupid when we all already knew the algotraders were going to bump it up to $20k again, at some point. The rest is just gravy. Don't buy it at the top, just like anything else.
