REUTERS/Edgar SuLONDON, Sept 27 (Reuters) - Bitcoin is struggling to go green, with the cryptocurrency making only slim gains in its usage of sustainable energy in the year to January, research by Cambridge university showed on Tuesday. Processing bitcoin transactions and "mining" new tokens is done by powerful computers, hooked up to a global network, that compete against others to solve complex mathematical puzzles.

Bitcoin mining is mostly unregulated and opaque, with few centralised bodies gathering data. The Cambridge study was based on data on the geographical spread of mining across the world and the energy mix of individual countries.
REUTERS/Dado Ruvic/IllustrationSept 27 (Reuters) - Celsius Network said on Tuesday Chief Executive Officer Alex Mashinsky has decided to step down and the bankrupt crypto lender appointed finance chief Chris Ferraro as its interim CEO. Before Celsius, Ferraro spent nearly 18 years at JPMorgan Chase & Co (JPM.N). Celsius also said Ferraro would serve as the company's chief restructuring officer. Last month, Celsius sued a former investment manager, accusing him of losing or stealing tens of millions of dollars in assets before the crypto lender went bankrupt. Rival crypto lender Voyager Digital, which also filed for bankruptcy in July, said on Monday that crypto exchange FTX won a $1.42 billion bid to acquire its assets at an auction.

"Bitcoin miners have continued to watch margins compress - the price of bitcoin has fallen, mining difficulty has risen and energy prices have soared," said Joe Burnett, head analyst at Blockware Solutions. That's put serious pressure on some players who bought expensive mining machines, or rigs, banking on rising bitcoin prices to recoup their investment. Shares of Marathon Digital (MARA.O), Riot Blockchain (RIOT.O) and Valkyrie Bitcoin Miners ETF (WGMI.O) have sunk more than 60% this year, for example, while crypto-mining data center operator Compute North filed for bankruptcy last week. "From managing their balance sheet, processing units and energy costs, miners will look to stay afloat regardless of current market conditions," he added.
