> Reliable and safe trades can now be done by a swarm of computers running free software, and they only charge a tiny margin over the costs of bandwidth, energy and storage. Do you have an example of such a market today? It's actually not NASDAQ that makes trades reliable and safe. Sure, they're involved in many trades, but the more relevant entity in this context might be DTCC [1]. The fact that almost no one here will have ever heard of DTCC before may help illustrate the size of the gap in understanding between the US securities markets today and "Let's use the blockchain to trade stocks for free."
