Bitcoin (BTC) is flirting with price levels that would have been considered highs in December 2017. That was when bitcoin first touched up against $20,000, only to fall precipitously, then scratch and claw for three years to reach $20,000 again by December 2020. Bitcoin’s price has fallen out of the $30,000 range over the last week and it has come dangerously close to breaking down below $20,000.
