This week, Bitcoin’s new all-times-high at $67,000 was in the spotlight for crypto enthusiasts. GetBlock invites you to cut through the noise and chaos and check some other records of this turbulent week.

Bitcoin at $8,000, for U.S. residents only

When Bitcoin, a flagship cryptocurrency, was setting a new historic high at $67,000, its volatility spiked to unbelievable levels. On major spot exchanges, BTC price dropped from $64,000 to $60,000, but recovered promptly.

However, on Binance.US, the US-incorporated unit of the world’s largest cryptocurrency exchange Binance, Bitcoin (BTC) flash-crashed to $8,000 level losing more than 88% of its price. This painful drop took place in no time: in less than 1 minute, Bitcoin price returned to ‘normal’ $63,000-$65,000 zone.

As explained by the representatives of Binance, this flash-crash was caused by the problems with a third-party data system of an institutional client connected to Binance.US via API instruments.

Crypto Twitter was guessing whether someone managed to buy Bitcoin (BTC) at $11,000. Eagle-eyed Redditors found at least one lucky trader who saw his order filled.

This order was placed when Bitcoin (BTC) price was below $12,000.

Polygon was in danger of $850 million hack (potentially largest in DeFi history)

Top-tier smart contracts platform Polygon (MATIC) paid the largest bug bounty in history of the decentralized finances (DeFi) segment. According to the Immune.Fi bug disclosure platform, white-hat hacker Gerhard Wagner submitted the description of flow to Polygon (MATIC) in early October, 2021.

As per the explanatory post, the design of Polygon’s Plasma scaling solution allowed the possibility of ‘double spending’: malefactor was able to resubmit the ‘request’ to withdraw Ethers or tokens from Plasma with slightly modified parameters. As such, an already validated transaction could be re-submitted for up to 223 times.
