Protip: any site you go to (like MEW, Binance, etc) you should hard code the domain name to IP address(s) in your host file on your local PC. Why rely on someone else when you can rely on yourself?
that might fuck you over later tho... what if they change servers/hosts? someone might even conveniently host a phishing site on the old ip
When I deal with money it's not a "set it and forget it" situation, yes, if they move hosts, or add new load balancer, etc, you're right. However just like you should regularly check for malware, you should make sure these types of safe-guards are up to date as well.
