For a generation of alienated techies, crypto's all-for-one ethos was its biggest draw. Now panic is spreading across this universe — and that same ethos is posing what may be the biggest threat yet to its survival.

What started this year in crypto markets as a "risk-off” bout of selling fueled by a Federal Reserve suddenly determined to rein in excesses has exposed a web of interconnectedness that looks a little like the tangle of derivatives that brought down the global financial system in 2008.

As Bitcoin slipped almost 70% from its record high, a panoply of altcoins also plummeted. The collapse of the Terra ecosystem — a much-hyped experiment in decentralized finance — began with its algorithmic stablecoin losing its peg to the U.S$., and ended with a bank run that made $40 billion of tokens virtually worthless. Crypto collateral that seemed valuable enough to support loans one day became deeply discounted or illiquid, putting the fates of a previously invincible hedge fund and several high-profile lenders in doubt.
