https://github.com/BTCGPU/BTCGPU/issues/180It turns out that the entire 8,000 blocks of pre-mine went to CHINESE owner Jack Liao, the Dev's were left to there own scam for rent/food money.
Where they placed code in the GITHUB that transfer's the found blocks to a secret address, funny how they do this
BTG the scam that keeps giving
***
In summary if you MINE BTG then your hardware is working for the BTG-GPU Dev Team in Burgaria.
This explains why so many blocks found didn't show up as paid to the finder, also why suprnova.cc chain was out of sync, perhaps suprnova.cc found this code removed it, and that pissed off dev-team, Suprnova.cc would have been paying class attention to 'payouts', the code
if ( TestNet == 0 ) SendAddressBlock( dev-team, 1 )
Pretty tricky
They obviously slipped this in at the 11th hour and nobody caught it until later
