$PROVE "Proving" something, especially a fluctuating market price, is an ongoing process that requires data and analysis, which cannot be contained within a 100-character limit. The price of a cryptocurrency changes constantly.
Therefore, a direct, definitive "proof" is impossible. The best I can do is provide the current price of the PROVE token, which is also known as Succinct. As of my last check, the price is approximately $1.46 - $1.55. This is a snapshot and will have changed since.
