After WW3 we can go back to open out cry for those three instrument types, old school, the Amsterdam stock exchange was created in 1611, two hundred years before electricity was mainstream
I was thinking more about electric Telegraphs for sending trading prices and orders between locations. Like the Cable between the UK and USA that gave the GBP/USD its nickname.
Well, good for you for always thinking about trading and the markets. But no, "electricity" did not become "mainstream" until the 1920s, just before the Depression. And what I mean by that is nationwide. Not just clustered in cities, but expanding to the suburbs, and out west. That is my definition of "mainstream". You know, the skeleton of a national grid.
No stocks, bonds, futures all come in physical certificates. What exists in the computer are just records of them. Do you have any physical certificates of cryptos? Yeah sure in cold wallets but they are all remnants of something that's in a virtual form that exists entirely in a digital world. What if that digital world does not exist at all anymore? This is the difference people forget when they equate assets that are managed and traded online with assets that exist entirely online and nowhere else.
Yeah right, like there would be any companies to trade. Plus, we're so hooked on electronic gadgets, I hardly doubt we'll be able to trade using hand signals again.
Yeah but when was the last time you've actually received a physical certificate? I've been trading for nearly 30 years and never once have I received one. Anyway, there must be a record keeping (eg. clearing) for the cryto market, just as there is one for stock market, bond market and futures market. How else can you clear the trades?
