I would pick bitcoin over usd anytime anyday, my reason been that we have seen the value of bitcoin risen from $3k to $11k within a period of 2 months, and how many percentage increment in value has the usd experience over the past one year? my thought.
It is true that USD did not make any good movements in the past or even will be in the future but do you think you can even eliminate USD or any fiats? No, I will still choose USD since we are still all depending on fiats. Btc has great volatility that makes its investors earn money but still, it has no intrinsic value, also not that used and accepted as payment methods.
