bitcoin is not a scam. You had admitted earlier that "the distributed ledger is a genuine technological innovation which demonstrates that digital records can be held securely without any central authority."
Bitcoin itself is not a scam.
Telling common folk to invest in bitcoin because it is safer than stocks, because it will be worth a zillion in a few years, because it will be the currency of the inerne, etc. -- that is a scam. Even, or especially, if supported by pseudoscience like the logscale straight-line extrapolation, the (total e-commerce)/(finite suppliy) argument, blockchain statistics passed off as usage statistics, etc. Especilly if the victim is not told that the price will depend on the mood of the Chinese tea traders, that no one will care if his bitcoins get stolen, etc..
(TelexFree had a non-scam product, some uninteresting VOIP card. The scam was getting millions of people to invest all their savings in the MLM scheme.)
Have you considered the scenario where bitcoin eventually becomes accepted and used by the majority of the people on this planet? Will the people whom you had advised hate you for that?
That is what I am very skeptical about.
I tell people
why i am skeptical. Ultimately it will be their decision to invest or not. I will run the risk of being wrong.
Have you considered the scenario where the price will crash to 100$ or less? Will the people whom you convinced to invest their savings at 800 $/BTC hate you for that?
