Hi!!
I see you properly read diff of bitbar, but completely lost block reward.
you can make and easy workaround:
Calculate reward = 1/(diff/0,000244140625)^(1/6) ; and your problems will go forever.
coin.block_reward = COIN / pow(coin.difficulty, 0.16666667)
Also, You can set default sort to adjusted diff, because it is awesome!
Thank You for this great site.
