I have made over $100 in BTC from the mining game. I used to be in 10th place but sold all my buildings for $30 and took a break. The guy in 1st has made over $3800 just of the mining game. Referrals give you a nice boost too. I am almost to 1000. It is a fun game. You can withdraw to a FaucetHub BTC wallet at 35,000 coins, any doge wallet at 50,000 coins and any BTC wallet at 100,000 coins or $3.50, $5.00 and $10.00 respectively.

Nice tutorial btw. Well done.
