$BTC Bitcoin traded lower this Friday, the 31st, ending a week of decline and volatility for the asset, which fluctuated in the face of a turbulent technology market due to the developments of the Chinese chatbot DeepSeek. In addition, the measures taken by the President of the United States, Donald Trump, involving the crypto sector continue to be observed.

Shortly before 5:15 pm (Brasília time), bitcoin fell 3.44%, to US$ 102,134.61, according to Binance. Ethereum, on the other hand, rose 1.54%, to US$ 3,313.47. "The week was marked by a drop in the technology market due to the avalanche caused by Deepseek, which also had an impact on the crypto sector, despite the rapid recovery. Bitcoin had a notable outperformance, driven in part by positive headlines detailing reserve bills in US states and by an increase in funding rates and trading volumes," says Fábio Plein, regional director for the Americas at Coinbase (NASDAQ:COIN).

"At the same time, MicroStrategy (NASDAQ:MSTR) continues its aggressive strategy of accumulating Bitcoin, recently acquiring 10,107 bitcoins for US$1.1 billion, bringing its total holdings to 471,107 bitcoins, valued at approximately US$47 billion," says Ana de Mattos, technical analyst at Ripio.
