Scammers are using international characters to impersonate legitimate cryptocurrency websites and steal your stuff
Homographic characters are international language characters, but with a hard-to-spot dot or inflection above or below beneath – e.g. ḥ ạ ṃ ì. There are quite a few characters that have this looky-likey quality - all of which can be used to register a spoof domain. Normally, a business would defensively register look-a-like domains, but in this case there are potentially so many possible combinations that this approach is likely unworkable for many. This probably needs to be fixed in the browser. Until that’s done, always scrutinise the destination URL of any website link (including the ones that you see in online Ads... such as those displayed in Google's search results).
If you see a non-English character in the URL of an English language website then you are looking at a sure-fire sign of a scam.
