There are several ways to protect your resources from being taken and finding the one that works best for you and your alliance should be easy. Below I will detail pros and cons of different methods that I am aware of. And there are probably even more than the ones I can think of.
Permanent Bubbles – If you are in a big alliance there is a chance you have a player who is determined to have the most might on the server. In order for him to do that he bubbles 24/7 so he can build wall and always be protected.
Pros – Resources constantly under bubble protection without the need to get passed around. Always, have plenty of carts and quick transport times.
Cons – Player must always be on to fill alliance requested and front the costs of paying for permanent bubbles. Player also must always know when bubbles will pop and be ready with next bubble.
Bubble Banks – Many alliances create a new account and use its 7 days of protection to bank resources.
Pros – Free bubble protection for one week.
Cons – Constant building of banks and upgrading to have efficient transport times and cost. Difficult to transport from one bubble to next before bubble pops and the next bubble is ready for transport. Players forced into switching accounts back and forth on devices.
Rein Bank – Store resources at a player who is open and reined.
Pros – This is fun just to entice fights and get tks for players. You can take turns being the bank and get many players good tks.
Cons – Very dangerous that player may go offline, get zeroed, and lose all resources.
Low Level Bank – Create a no named low-level account and put in a friendly alliance. You transport goods to it and attack when you need resources.
Pros – No one needs to be on bank to transport goods. No need to pay for bubbles and no chance of losing troops trying to defend.
Cons – If someone ever found your bank they take all resources without a fight. Easiest bank to get robbed but low-level players are very rarely hit, especially on an older server.
Resource Balls – If you have an alliance where there are always active people you can just pass resources from one person to the next.
Pros – Someone is always online able to distribute resources. Sometimes players will bubble for short hours and then transport when they are leaving.
Cons – If you have too many resources that can’t be transported easily this plan would never work. There is always a possibility someone speed attacks before you have time to transport to next person.
These are just some banking techniques that I have come across and I’m sure there are more. The only reason I know so much about banking is that I love to be a bank robber and try to steal from as many banks as possible. And I’m not going to reveal which method I use. Main thing you should get from this is that there is no need for you to store or hoard resources unnecessarily. Things like vaults are a waste of space, just look for a better way to protect your resources. Happy hunting.
