Hello,
if you are still wasting time at RollerCoin (like me), please be aware of fresh change today.
Recharging elecricity is not free anymore at https://rollercoin.com/?r=kv6v7g3v
On top of that, apparently your mining power will decrease if your elecricity is low.

Lucky enough for us cheap players, the elecricity can still be got without much investment.
Battery can be purchased for 60 RST (season currency). With some small discount if you purchase 5 baterries at once.
Basic supply of RST is quite easy:
- 10 RST daily for 1 game played = super easy
- 4 RST/day for same weekly quest = super easy, just weekly
- about 50 RST each week from leveling event
- 25 RST a day for 30 games played (that is some work, but also has other rewards)
- 2x 15 RST a day for 15 specific games played (can be easy or hard, depends on game)
So with some games play, you can keep steady inflow of batteries.

I dont know yet, if you need 1 battery a day, or always recharge to full. Lets see in few days (but of course if you let power to drop, you loose some income).
Anyway, at this point, I have enough RST to feed my miners for long time. Im mostly curious, how it will affect overall power (maybe its even good thing, if it decrease power of competitors for me).
