CZ only tweeted and he's not asking our opinion. It's YOU who is asking. Change the misleading title.

It seems you're misunderstanding the meaning of the word beginning. It doesn't say every other country will follow El Salvador's footsteps. The questions should have been like This is really a Beginning or will it end with El Salvador?

Now, to answer that question. I think countries that are friendly to BTC are still observing what's going to happen. If the implementation/roll out of government policies concerning BTC will be successful, their neighbors could follow.
