So i purcahsed some btc from circle.com and I used credit card and before being able to enter card details it asks for last 4 digits of ssn number so i put it on and purchased the btc. after purchasing the btc i sent them to helix light to get tumble then from their to the market i am ordering stuff on? since i put my last 4 digits ssn is it a danger even after tumbling my coins or am i safe??
