but it doesn’t do anything to dispel the notion that Bitcoin is a bubble ripe for bursting.
I agree that its in a bubble. But so are most other asset classes.
Property is in a bubble, the stock market is in a bubble, and both of those are in a bubble because governments keep increasing the money supply.... which goes back to my point about central banks constantly printing new money.
I wouldn't spent $20k on a bitcoin, because I think there will be a huge correction, but I think the blockchain and the idea of limited supply of a currency is the future and will replace our currently highly flawed system of exchange.
A gold backed digital currency on the blockchain would genuinely change the planet.
Bitcoin is the pioneer currency, the pioneer seldom triumphs.... but is difficult to deny that blockchain technology could revolutionise the world and probably will replace fiat currency in some form (probably governments each having their own national currency with a blockchain).
ps. When you say debit card, do you tend to pay by contactless? Because most other people do.... and you can pay with crypto in the same way that people pay with paypal or apple pay pretty much instantly.
Physical cash is going to die irrespective of whether crypto succeeds or fails. It already is dying out, people have gone contactless and zapping things with their smartphones already. I can't see physical coins and notes lasting another 30 years even if we stick with fiat currency.
