London-listed companies released updates on their activities last week.

The Bitcoin mining company based in the British Virgin Islands, Vinanz Ltd, increased its bitcoin mining fleet in Nebraska by 50% with the addition of ten Bitmain Antminer S19k Pro 120 Terahash miners. It now has thirty S19k Pro 120 TH miners. According to President David Lenigas, “Nebraska is an important and growing hub for Vinanz's Bitcoin nexus in North America. With an electricity price of only 6.5 US cents per [kilo watt], Nebraska is proving to be a real winner for us when it comes to keeping operating costs low. The company is convinced of the future of Bitcoin, which is why continuing to expand in the United States and Canada is our main business objective.”

For its part, the London-based life sciences investor NetScientific PLC, for the quarter ended in June saw its net loss reduced to 8.3 million USD, or 0.23 USD, or 0.23 USD per basic share and per diluted share, compared to 11.5 million USD, or 0.37 USD the previous year. This decrease was due to lower operating expenses from $12.7 million to $8.7 million
