The amount of money that gets stolen daily over crypto is pretty big too. So I’m not super convinced it does a particularly good job in that regard. Like, “it’s more safe and secure” is not the hot take I would’ve expected on the same day that Celsius Network collapsed stealing everyone’s savings.
=> /proof-of-work As we’ve discussed many times before, cryptocurrency is:
* inefficent
* wasteful
* unstable to the point of uselessness for transactions
* expensive (gas fees)
And, it requires that I trust all 8 billion people out there so they don’t talk shit about my fam immutably on the blockchain.
