I have done many transactions on coinbase. some small and some well over $1000 and higher. I did upload my DL and some personal but I was NEVER asked for my SSN. Today I try to make a small purchase and I get a pop-up stating I must give my SSN to buy the coin. When did this start??? just a few weeks ago I spent over $1000 and it was fast/smooth without any need for additional information. What changed? anyone know when and why?
