>Bitcoin is useless because it can't be used as a currency > T Bill's and bonds are not currency, they are investments and they are very stable the way investments need to be. Your original claim was that bitcoin is useless because it's not a currency. If t-bills and bonds are useful despite not being currency then have you abandoned this position? Anyhow, they're stable if you believe the US federal government is stable. Given everything that's been going on that's far from a sure thing. >Price spikes are not hysteria per se. There is no regulation so the price can be manipulated. Coversely, state regulated assets can be manipulated too... by the state. >The hysteria is when people throw their money at stocks because they make some claim about exploring block chain. It's when billion dollar investment companies all decide to diversify into bitcoin at the same time and create a frenzy. Sure. Bubbles happen. That's life. They're not unique to crypto. >And when it happened that was bitcoins chance to become adopted and it failed. Ah yes. Like how the .com crash meant the end of internet businesses forever.
