Crypto Rebounds as China GDP Beats Estimates and Arbitrum Advances 6.7%

Digital asset markets moved higher on Oct. 19 as global equity futures rebounded following third-quarter macroeconomic data from Asia ¹. $BTC traded around $82,500, recovering from a Sunday drop to near $80,700 and maintaining ground after briefly slipping beneath $80,000 on Thursday ¹.

The broader rally coincided with an advance of more than 1% in Nasdaq 100 futures and firmer Asian equities after China reported third-quarter GDP growth of 4.5%, topping forecasts while crude oil prices receded ¹. The macro lift follows a steep pullback in US technology shares, marked by the Nasdaq falling 4.5% over the prior week amid concerns regarding debt loads and corporate spending on artificial intelligence ¹. Market participants previously tracked similar macro trends when Bitcoin traded near $82,500 as Chinese GDP growth outpaced expectations.

Cumulative volume delta across majors printed flat to negative even as notional open interest outpaced spot price moves, suggesting persistent aggressive selling into long positioning ¹.
