i think to make things easier for people new to btc there was an addition of creating a btc address from your email, but i believe if you sent to the btc address 12VmJciWNFmUiDmb2zKCxkp5HvAacAnn8P that once the lottoshares are public you would be able to retrieve them through your banx.io account.
Ok, now I understand, it is to choice, one way or the other.
I think I will choose the way it's written, I find it easier, and that the key to import banx.io not know how to do haha.
Thanks nexter.
