Always check the site you are always using and if possible avoid google when searching for the site because there are times when the ones that appeared are those scam sites with just one letter in the address different from the original one and its interface is just the same so if you carelessly input the password then you will be hack and all the coins that you hardly earned will be gone. After using a legit site, bookmark it and access it from there. Do not participate in HYIP as most probably it will be just a scam and you will lose your funds.
You are probably saying the total opposite. If you have found a site, the best thing to do is google that site. This way, if the site is actually not
legitimate and a scam, you will find some reviews about it being a scam on some forum or blogs. Also, google most of the time can detect phishing sites and skips them from the search result.
