Why is the deposit adress changing? I bought 0.69 BTC yesterday and wanted them transfered on my JD account. My wallet at the time was 1PpyrMf787iuS5jSEKR8gb96KmrXNjfgG2. Today I log in to see that my wallet has changed to 1HwKzAgXe6zAnTuUQEJwwXNwLC6tHTNvo2. It is writtten that I can use my old wallet if I want but will the coins be transfered to my account or are they lost in the process?
You can use the old address and it will go into the same account.
