U can't mine when there is NO block-chain,
No working software
The 'testnet' is just redirection of millions of sols/sec to other equihash currency, .... all is a scam.
Even in the past two hours btg.suprnova.cc has suspended the testnet until there is working software and a block-chain.
This coin will launch as stated on a new chain.
What is a 'launch'? What is a 'fork', in the absence of working software, are all now in alice in worderland??
The 'fork' never took place oct25, no working software in place at time of 'fork', a snap-shot and logging a block number is not a fork.
The 'launch' actually the 4th deadline to come&go since 'fork', 3 hours ago new code released, and it has failed.
WRT to btg.suprnova.cc they have turned off the testnet until there is working code, they're attempting to download a working block-chain, but it may take a week, as there are no seed-nodes in chainparamseeds.h. ( again dev's don't care, or are trying to slow down the easy mining to the public )
Pool.GOLD is still running the scammy TESTNET. It has been running 3+ weeks, and its re-directing +1Million sols/sec of equihash to profitable z-coins.
BRAVO for btg.suprnova.cc for not ripping off their customers, I agree there should be NO mining of BTG until a 100% block-chain exists, and that may take a very long time.
My chain is now 98% and its been running +7 days, a very slow process.
