Is Opera Browser Safe?

hello everyone, Is Opera Browser Safe? or maybe opera developer can spy user INFO like password?
they have free built in VPN, it safe to use opera VPN and checking your Gmail inbox While opera VPN is On?
Specially Im asking about Bitcoin Exchange, Is it safe to save Exchange password on Opera Browser ?

The browser is safe. The VPN is free, fast and unmetered, meaning it's used by many people and abused to hell, the chances are that those ips are already blacklisted or they can become blacklisted in any moment. I wouldn't use the VPN to log into accounts you care about.

Speed dial and bookmark fantastic and beautiful.it is fast ,it protects your data,chrome extensions work.
