If fixed supply can be infinitely inflated (when it comes to price) and thus creating a bubble that can burst, it is not being different from supply that is not fixed.
Example, current Bitcoin price inflated by Tether printer with no real backing.
Fixed supply of BTC doesn't matter, when the price can be infinitely inflated by Tether printer.
Excuse you!
You just decide to wake up and you decided to choose conspiracy theory and sentiments. Is Bitcoin value actually pegged to USDT or to USD? Another question I have for you is USDT that is use to detect the value of Bitcoin or USD, in addition is USDT the only stablecoin that is not back by anything that exist in the crypto market? What happen to the likes of USDC and other centralized coins that are not back by anything but bonds and treasuries.
I don't support USDT policy but indeed they are not back by anything, the security exchange commission would have bring them in for questioning and the ponzi scheme would have collapsed by now. Enjoy the moment, Bitcoin has survive for the last 11 years and would do more without anything bad happening to it, if Tether should even collapse today, Bitcoin would definitely increased in value than before.
