As You are having the possibility to earn and spend Atheios, we will allocate You a bloxxchain ATH account once registered and we need to know to which ATH main account to transfer funds back,once You want to withdraw them. So a registration is needed in order to play. But - hey - is is free and without obligations. And You can according to GPDR remove Your account anytime.

We'll never share your email with anyone else.
This should be Your main account address, as we will send money to this one if You would decide to withdraw funds from Your bloxxchain ATH address.
