Today I snagged a limited Armageddon miner for 15 rlt. With the weekly quests I'll get 10 rlt back for that purchase. So it's an easy 7000 gh/s per rlt spent. A sight cheaper than your average miner in the game. With a .75 percent bonus power as well. I try to not spend rlt unless I can get atleast 6000 gh/s per rlt. Slowly grinding up miners that are cheap deals focusing on ones with bonuses over .5 as that's where most the people on the leaderboards power output comes from. Not really sure if that's from the bonus or from referrals but either way the bonus stacks on all your miners so it can't hurt. There is only 3500 or so left out of the 7000. Come on in and get you one before they run out. Sign up with my link and get 1000 Satoshi's. I get bonuses from your referral and you could too.
