That is one of the reason i don't subscrib to this issue of giving out very sensitive infomation about myself except for the basic ones,i know of a friend who lost huge sum of money to scammers because of this.
I have seen many Hyips asking for your phone number. There was this big Hyip company that appeared legit and they even created an app on Playstore. However, they turned out to be a big scam.
