hello, I haven't bought bitcoins in over a year, and the sight I originally got them from is now down. What siites do you guys use / recommend to pruchase from? Also, what is the preferred method of bitcoin wallet? I used to just do cold-storage on usb flash but I've really fallen off the bandwagon with this stuff so was just hoping to get feedback as to whats currently the most up-to-date methods for purchasing anonymously and storing coins. Thanks.
