However, one senator saying that Bitcoin becoming legal tender is not a matter of opinion does not actually make it less of an opinion. Adoption would be required by the majority of MPs and/or other authorities (I am not sure which institutions have most power over economic regulations like this in Mexico). One senator isn't enough.
Didn't El Salvador also not abandon their fiat, which is the USD? I remember reports that the actual amount that the state is keeping in Bitcoin is very small. Moreover, do we really know how (if at all) Mexico will adopt Bitcoin (I mean, in detail, so that we could assess how similar or different this is to El Salvador)? Is there at least a project law already?
First, you argue that the opinion of one senator doesn't really mean anything, and then you ask the question whether there is any kind of project at all? Isn't that completely illogical? This whole thing shows the absurdity of the basic understanding of things that, for reasons of news recycling, are brought into completely meaningless connections.
El Salvador has a president who is part of the ruling and majority party in the parliament and who is pro-Bitcoin, and Mexico has a senator in the parliament who has a fantasy in his head...

Seriously? After hundreds of pages on the forum on that topic, you ask this question? The USD has been the official currency in El Salvador for more than 20 years and it is still the same today.
