I just got a phone call from a London based number, from a woman speaking with an eastern European accent, who claimed to be based in Switzerland and working for a company called coinmaster.com. The first thing I asked was where did you get my number... Apparently the marketing department. She claims that coinmaster is in partnership with JP Morgan Chace and that they are pre-ICO and wanted me to sign up to their website. I told her to get lost since I knew it was a scam, hung up the phone and blocked the number. Seconds later I got a call from an 'unknown' number, the same woman again. At this point I just told her to fuck off and hung up.
If you see coinmaster.com, know that it's a big fat SCAM!
