This is simply another step toward Bitcoin's progression as a global currency. We can't really foresee what happens next, but this law helps encourage others to use Bitcoin as a means of payment, keeping it away from being considered an asset. The more laws created regarding bitcoin and other cryptocurrencies, the more support they gain, especially for merchants. We can't see the immediate impact of this, but I believe it will make a positive contribution to the crypto market. Let us prove to the people who think it was impossible that they are wrong and change their minds.
I guess you haven't taken the time to research the GENIUS Act that was just passed in the US, it doesn't mention bitcoin or altcoins. The GENIUS Act is a specialized bill and focuses solely on stablecoins. So there will be no impact or push to turn bitcoin into a currency or payment method.
So far, bitcoin is only recognized as a commodity, asset or investment and I don't think they will change that anytime soon and encourage people to gradually use it as a currency. The simple reason is that governments will never accept a currency that they do not control.
