How many bitcoins are being mined per day

However, it also suggests the amount of electricity consumed every year by always-on but inactive home devices in the US alone could power the entire Bitcoin network for a year. In order to "mine" Bitcoin, computers - often specialised ones - are connected to the cryptocurrency network. This process involves solving puzzles, which, while not integral to verifying movements of the currency, provide a hurdle to ensure no-one fraudulently edits the global record of all transactions.

As a reward, miners occasionally receive small amounts of Bitcoin in what is often likened to a lottery. To increase profits, people often connect large numbers of miners to the network - even entire warehouses full of them.

Environmental conundrum

That uses lots of electricity because the computers are more or less constantly working to complete the puzzles. The University of Cambridge tool models the economic lifetime of the world's Bitcoin miners and assumes that all the Bitcoin mining machines worldwide are working with various efficiencies. But commentators say the investment clashes with the electric car firm's previous environmental stance.

I don't know how he can walk this back effectively.

Their subsidy needs to be examined. A carbon tax on cryptocurrencies could be introduced to balance out some of the negative consumption, Mr Gerard suggested.

What was the code change to fix that? ColinDean You seem to have been halving the total revenue per day, but for the exact result you'd have to halve and rounddown to integers the subsidy per block. This is due to less than full satoshis not being paid out. I didn't use your code though. Can you share your code?

When I calculate using satoshis as a number instead of a whole bitcoin as double and take the floor of the halving, I get the same result. I'm probably making a stupid error somewhere. ColinDean: I think you are rounding down per day , but you'd need to round down per block. I used a Google doc, I'll share it when I get home. Start with 50 btc instead of and multiply with after rounding down.

I see what you mean, now. You're definitely right. I'm rounding per day.

So in , it's only BTC per day, and it's going to be even less as we move further and further! For current and future readers: This calculation doesn't give good results for later years, as it doesn't account for block rewards only paying out whole satoshis.
