How can this possibly be the same? Again: imagine a stock of a company that is very profitable and has stable cash flows and there is no indication this won't continue. Pekelo's claim was that this stock trades only at what people think it is worth. Everything, according to him, is valued by supply and demand. I disagreed and said that a stock may have short term fluctuations but if people valued this stock for whatever reason at a small fraction of its discounted future cash flows someone would come in very quickly and buy the entire free float of the stock. Fair value and the actual price can be very different. Crypto currencies are not backed by anything, not by any future cash flows or the expectation thereof. That was the difference I pointed out makes sense now?
This isn't really a disagreement with Pekelo's point. He said both TSLA and BTC have value because people think they have value. All you've explained is that the belief 'TSLA has value' is arrived at by some means X whereas the thought 'BTC has value' cannot be arrived at by the same means.
