Both these addresses are being used for the same scam. Noticed BTC giveaway on https://www.youtube.com/watch?v=kF9QNuo3Ih8 via Chamath Palihapitiyas company. The video relating to it is on YouTube at https://www.youtube.com/watch?v=kF9QNuo3Ih8 via mobile but not desktop still? Was told Chamath Palihapitiyas company was givingaway BTC if you gave a small amount above 0.1 BTC you would get your investment back plus a small BTC gift. This was also run on chambtc.com and chambtc.us.
