採掘をはじめたら、長時間放置せずに
頻繁に他の採掘施設に移し替える事をおすすめします。
Once you start mining, we recommend moving frequently to other mining facilities rather than leaving it unattended for long periods.

赤線で囲ったところが、攻撃した時に奪える報酬です。
まだ奪える報酬が少ないで、他のプレイヤーから攻撃される可能性は低いです。
The image below shows a facility that has just begun mining operations.
The areas outlined in red are the rewards you can capture when attacking.
Since there are still few rewards to capture, the likelihood of being attacked by other players is low.

赤線で囲まれた所を見ると、奪える資源量が多いですね。
他のプレイヤーから、攻撃され奪われる可能性が高くなります。
その為、相手に物資とポイントを奪われる前に、他の採掘施設に移動した方が安全です。
The image below shows a facility nearly 7 hours after mining began.
As you can see in the area outlined in red, there's a large amount of resources available to be taken.
This increases the likelihood of being attacked and having your resources stolen by other players.
Therefore, it's safer to move to another mining facility before your supplies and points are taken by opponents.
