The monotonous computer generated voice in that video was extremely annoying.
You don't utilize Bitcoin, but transferring it from one address to another. A car can be both, utilized and transferred. Bitcon can only be transferred. That's why one cannot use it for want satisfying. And that's why it is worthless. If the only thing that one can do with X is transferring it to someone else, then X is worthless by definition.
Modern cars lose 14+% of their value every year though too so they're not great for transferrability and recouporation.
Cash can't exactly be utilised? Interest is a by-product of inflation and how well an economy is doing. If you sit with cash in your house, it's losing you money.
Gold is not valuable due to declaration but due to utilization in dentistry, medicine, electronic, aerospace and jewelry. Bitcon can only be valuable due to declaration.
Well not really. Gold is a bit like Bitcoin now.
Most medical, electrical and chemical equipment uses platinum instead of gold since it's cheaper (even though gold is more inflated).
There are fairly worthless financial instruments people like to gamble with all the time and bitcoin may or may not be one of them. It's certainly getting a lot of hype but I don't think it's going to be the main coin in the future for payment systems - I'm not sure if a true cometitor ahs yet been found yet though either. Money was initally created to be a store of value, a promise that you'll get something for the gold you carry. As time went on it got stored in banks and people just transferred signed receipts to retrieve those funds, and then came fiat currency after that which currently aims to keep an economy growing for as long as it can by using inflation.
You're not meant to hold a lot of cash anyway, maybe the same can be said for bitcoin and you're meant to invest or hold other assets that actually pay you back (also there aren't many banks in first countries at least that acutally pay higher than inflation in interest).
