This is just a perfect example of not your key not your coin as I thought I am reading a positive news about Mercado customers that have crypto on the exchange after it has been hacked.
https://tradersunion.com/news/cryptocurrency-news/show/4103231-mercado-bitcoin-reopen-after-hack/From what I read the exchange has been closed down, it will be reopened in a way customers can view their balance on Monday but withdrawal will not be possible until further notice. I do not yet see anything positive about this.
Everything shows that they took this time rushing to receive financial aid from investors to fill the hole
They do not have enough to take the loss, I think Tether will help them for a big share of the company

But they said again that no one will lose anything so I think I believe that they will come back.
This was the last update:

In this first phase, which begins on November 9, access to the platform will be available via the website, allowing you to view your balances, statements, total assets, and investments.
Additional features—such as transfers, withdrawals, and trading—will be reactivated subsequently, as each module completes its final security validation.
