I admit I don't understand bitcoin, its attractions (the arguments seem similar to gold), and it's down almost 50% in 3 months, so much for the superiority to "fiat". It's not for me, but then I'm not young or in accumulation mode; it seems more like a hyper-speculative stock, which has its place.
I do think the energy wastage and govt regulation a la China are obstacles (maybe only speed bumps, maybe not). The yewt bought a couple back 6-7 years ago, only he lost his wallet when his computer disks crashed, a bit like piling up your cash and burning it. I realize this is not the norm, but ... neither is it reassuring. I think he and his older brother the winemaker are using their computers when not in use to coin Ethereum, so it doesn't seem to discourage him.
It's not for me, but could be for you, I guess.
To quote Blake:
Mock on, Mock on, Voltaire, Rousseau;
Mock on, Mock on, 'tis all in vain.
You throw the sand against the wind,
And the wind blows it back again.
