With how volatile the value of Bitcoin is I don't know whether or not they feel safe trying to take that money and reinvest it you're walking by one of the coin ATMs that's at one of my local stores I've watched the value of Bitcoin halve its value than double it overnight basically every single day for the last 3 weeks
they should be doing that, otherwise I don't get how they are making any profit with those huge electricity bills. Last time I checked it, with electricity prices it wasn't worth it to mine cryptocurrency.
I did find some information about this, and have posted about it in the thread, and you are absolutely right about this in regards to Bitcoin, I did not find a lot of information about other crypto apart from Etherium, which claimed that the energy use of one Etherium transaction would not consume any power at all, which I doubt.
Ethereum uses proof-of-stake, there is no "mining" in a traditional sense, so its power consumption is more akin to e-mail than mining crypto. But proof-of-stake leads to centralization over time, which is antithetical to what Bitcoin people want.
