To estimate how much electricity is being used for the entire Bitcoin network, a peer-reviewed article was published on May 16, 2018 in the journal Joule . The estimates Alex de Vries came up with are that the current minimum use of the BItcoin network is 2.55 gigawatts, which is almost the amount used by Ireland.

Many times we don't think about the consequences that the BTC may have in the future, it has been a great revolution, that has kept with great expectations to the market of the economy, that in great part has placed all its hopes in it, but if we analyze these data that generate an alarm could generate great concerns, I don't manage the reliable data, but it is said that in my country there is a great boom with the history of the Btc, the mining has become the most sought after business, as a way out of the great crisis we are going through and the devaluation of our currency, what keeps many families afloat is the exchange of other currencies, including crypto, but there are already regions with serious electricity problems due to mining and the poor maintenance of power plants due to the poor performance of government agencies, in short, already the havoc is being perceived, so they spend long days without electricity, it would be great if the steem becomes the successor currency to the btc.
