I was thinking the same thing. Not only were there errors in the text, but the narrator also verbalized the same errors.  I think today people are pretty trained to look for things like that when trying to spot a scam. Of course most of us know that the people behind Coino don't speak English as their first language, but still I would expect a professional company to at least have a native English speaker do some proofreading for their website, press release articles, and videos.  So far all of them are lacking proper English grammar.
