Institutional buying of cryptocurrencies has wavered in recent weeks as portfolio managers continue to track a massive decline in asset values. Bitcoin is currently languishing below $33,000, having declined 50% from its May peak. The combined market value of all cryptocurrencies plunged below $1.4 trillion on Monday, virtually halving last month’s high.

While on-chain metrics seem to show favorable signs of a bottom — namely, that Bitcoin is being scooped up by long-term holders at the expense of newer wallets — market sentiment remains overwhelmingly bearish due to negative headlines. China’s ban on Bitcoin mining, an ominous “death cross” for Bitcoin and Grayscale’s giant BTC unlocking in July are just some of the headlines weighing down investor sentiment.
