Have you ever heard of diamond dwarf mining?
Unfortunately, you do not give money for your registration, but you can get more than 200% of your money on your payment, and I would recommend a 1000 Rubos deposit, which is around $ 15. You can get 3 dwarfs from the best.
You're going to take dwarfs, preferably the better and the more.
Once you have collected all the crystals, collect the crystal under the Store of ore menu item.
If you have just collected it, you have to have an internal and external balance here. You can not get the inside out, but you can remove the external balance at any time. Inner outer, 70-30%.
You get the daily bonus if you do not pay, so here you can only start it.
