This is the address for Gulden Development. From block number 1030000 this address will receive 40 Gulden for each block and from block 1226652 80 Gulden. That's why we don't show incoming transactions here.

The development reward is worth $9300 a month with a price of $0.0068
I am comfortable to start buying above 50 satoshi for a longer term hold. $9300 a month is not much for a development team and other expenses they might have. The GAB has also promised the reward will never increase, only decrease when the price goes up. The max supply will always remain 1.68 billion in 2055 according to the OP.
