1. "Bitcoin's main differentiation is its decentralization and limited supply." That's the case for most cryptos.
2. "You can transfer billions of worth to the other side of the planet with almost no fees and nobody can stop your transaction or take your BTC." That's false. The cross border payment system sees trillions worth of money being transferred each year. In the last three months of 2023, Visa handled $3.9 trillion of volume and Mastercard handled $2.4 trillion of volume.
You can repeat that BTC is the future as much as you want, it doesn't stop the fact that it has no use case.
