US crypto mining used more power last year than all the computers
Reminder: good estimates place the number of people in the cryptocoin system in the 100,000s. BTC can support c. 7 transactions&#x2F;sec. Ethereum c. 20.<p>This is a scam. It&#x27;s a self-organizing pyramid scheme. There is no &quot;there&quot; there -- the vitamins really arent a cure for cancer, and your friend telling you to buy a warehouse full is part of a cult of pushers who are desperate that their warehouses of vitamin pills (ie., tokens) doesn&#x27;t become entirely unsellable.<p>All the numbers reported by the cryptocoin system are made up: these are manipulated markets with almost no buyers. &quot;Market cap&quot;s are inventions. The amount of actual liquidity in the system is tiny: people are looking for the exists. These exits are mugs called &quot;hodlers&quot;, ideally, You, who&#x27;ll buy their vitamins from them.<p>Usually, HN comments ought be somewhat more sober -- but I think this is now out of line. Sobriety in this matter is enabling a system of exploitation which should not be entertained by decent people.
