Did anyone follow this news? I just saw it, they also, just a few hours ago, submitted a law legalizing crypto payments.
Since the collapse of the FTX exchange, many countries drafted several new rules and laws against crypto companies operating in their respective jurisdictions, the current example of Brazil, we know Brazil currently has several crypto exchanges, for example: Binance alone has two offices in Brazil operating at the moment.
From the news/sources that you display here, the steps for the Bill from the Brazilian authorities, in my opinion, are only one, namely:
This would hypothetically protect customers from corporate malfeasance and other crippling events such as exchange bankruptcy.
Nothing more, Brazil cares about crypto users especially its people stay safe, they want to protect their people against problematic crypto foam, care about the bill.
