Other cryptos

In order for BTC to serve as many transactions as VISA it would have to use, roughly, more than half of global energy production.
I made a mistake & deleted my post.You're talking nonsense
That's not how BTC transactions work. There are about 2000 Bitcoin transactions per block or every 10 minutes
Lightning Network does not need mining computing power and can scale to millions of Bitcoin transactions per second
"Bitcoin currently consumes around 110 Terawatt Hours per year — 0.55% of global electricity production, or roughly equivalent to the annual energy draw of small countries like Malaysia or Sweden."

It would use less, a third instead of a half, but a third is still way beyond anything that we can afford.
Lightning network, aliens, Satashi Nakomoto, yes, yes, i know.
So what are you trying to say ?Number of transactions per block has no relation to the Bitcoin network's energy usage aka network hashrate aka computing power
So what are you trying to say ?
That it will use the same amount of energy as now, but will be able to serve as many transactions as VISA ?
