and one of the more interesting ones is that they will try to force people to pay stuff with bitcoin and not immediately transfer it USD.
That's indeed interesting and El Salvador seems too perfect right now; Hopefully, there's no ulterior motive behind their upcoming wallet.
but how will they be able to use the 30$ worths of bitcoin if they don't want to use the wallet.
They can't... Chivo wallet is the only way.
It's good that they're not forcing Salvadorans but not sure if there's a big difference between that and the fact that they're indirectly persuading
[with good airdrop based on their standards] them to download it.
