Yes I remember…. it was something about Coinbase with my link on it …. something of buy $100 BTC and you and I receive $10 using my link or something like that…. I posted some message to Facebook awhile back ago… and I really received $10! Now in your case if you bought $100 BTC they give you $10 extra Total $110 BTC… using my Link..now Coinbase is doing something different…but that was , was happening during that time me and cellphone typing on Facebook..
