After another week of red numbers, the total cryptocurrency market capitalization slipped from $1.93 trillion to $1.78 trillion. Bitcoin, the world’s oldest crypto and the largest one by market capitalization, lost nearly 10% of its value in the last 7 days, plunging through a key support level at $40,000. The price movements that took place last week generally validate Bitcoin’s status of the crypto sector’s barometer, as many major coins and tokens followed BTC’s example and ended up suffering similar or even greater losses.
