Just want to remind everyone and the beginner and experienced traders / users about the danger of phishing sites. Before entering your passwords and personal keys, look carefully what is written in the address bar. Learn by heart the sites of exchanges.
If there is one extra letter in the address bar or a dot or a double letter, this is a cloned site (scammers). It looks the same, everything is like on original site, only in the address bar an extra letter, a digit.
Today I switched over the link to watch the course and got on a cloned site. Be careful always.
Metamask could do the job,browsers should be protected to because most of the hackers are taking advantages to the holes from these browsers,normally these phishing sites are identical to the orignal ones only the urls will be different so you better install the metamask extension because it will protect your private keys from these phishing sites,also you will get notified when you are entering potential phishing sites.
