I dislike discussions of Bitcoin and the power required to secure the network. If it came down to it, the whole network could be secured by a single solar panel! The issue is there is always going to be competition to get the block rewards, and the only way to get a higher chance of ‘winning’ is to have a more efficient mining device or larger number of mining devices. More mining devices results in more energy being used. The energy use issue is down to greed for block rewards. Or am I completely wrong in my understanding? #bitcoin #mining #energy
