wow and if it is one chance per wallet then it'll be much much less than a 2% chance 
It's per address (believe single transaction). When you transfer to your addresses, make sure that transaction exceeds the minimums if you want to qualify. You can use advanced coin features to combine coins together into new addresses as needed.
right on, I had just made a new wallet and made receive addresses for each chunk of 50k I have
so I was hoping it was per address thanks for the info
