If you have account at Coinmarketcap (that is owned by Binance exchange btw) you should think about changing email address and use new unique password, because of the hack that happened on October 12 that leaked 3,117,548 email addresses!
Consider that email address you used for CMC account is now compromised, don't be surprised if you start to receive some spam and scam emails, so you should not use it anymore.
Coinmarketcap confirmed that hack happened and today they released blog post claiming that there was no password exploits, but only email addresses and they still don't know exact cause of the hack.

During October 2021, 3.1 million email addresses with accounts on the cryptocurrency market capitalisation website CoinMarketCap were discovered being traded on hacking forums. Whilst the email addresses were found to correlate with CoinMarketCap accounts, it's unclear precisely how they were obtained. CoinMarketCap has provided the following statement on the data: "CoinMarketCap has become aware that batches of data have shown up online purporting to be a list of user accounts. While the data lists we have seen are only email addresses (no passwords), we have found a correlation with our subscriber base. We have not found any evidence of a data leak from our own servers — we are actively investigating this issue and will update our subscribers as soon as we have any new information."
Breach date: 12 October 2021
Date added to HIBP: 22 October 2021
