On op it says that it's 25.88 million but I have heard that the final supply will be about 12m after pow. Could someone explain why it's going to be 12m instead of 25.88m?
Because many POS blocks are being mined instead of POW blocks.
How long does Bittrex usually process withdrawals for BYC? It's been 20 minutes till the status was 'completed' but it still doesn't appear on the blockchain.
I've had a big variation in it lately, few times it has taken well over 30 minutes, but usually in couple of minutes or even seconds.
