Rollercoin has weekly quests where you can get 10 rlt for finishing 10 quests. Along with plenty of rst that you can exchange for parts along the way. You really have to spend 30 rlt to accomplish the 10 rlt as the last 2 quests are locked behind a spending wall. Even so if you buy something for 30 rlt and get 10 back that's 33 percent off. If you get lucky you can find a weekly offer for less say 10-20 and you can get a miner for free with the 10 rebate if it's 10 rlt or 50 percent off if it's 20$. The parts you can get from weekly quests total about 5 rlt in value assuming you never hit anything over common in the season case. The best part you can accomplish about 4$ in rlt from parts a week without spending any rlt at all. Come give Rollercoin a try and get 1000 Satoshi's on me. I get paid for your referral you could too. Spread the love and keep on rolling. https://rollercoin.com/?r=kxdo2j26
