From what I've read, premining is going on at pool.gold and if you are mining there well you won't get anything for it all as it just goes to developers. When they are finished at 1-1:30AM UTC, they will open it up for everyone else. https://pool-gold.slack.com/messages/C7L8HMSQP/  If you want to follow the premine and see how much time until 499407 is reached then height is shown at http://btg.altpool.pro
