Each deposit you make to your bank account is randomly either halved or doubled. Same for each withdrawal.
Correction (tip o' the hat to Wrongfellow):
Each deposit you make to your bank account is randomly either halved or multiplied by three halves. Same for each withdrawal.

so you receive the amount you ask for but your account shows either half or twice the amount? |
|
| |
if your account is with a supermarket - your total shopping bill could be halved or doubled as well. oh, don't financiers have fun! |
|
| |
[sqeak], do all the other depositors get to make comments on your deposits? |
|
| |
Uh, wait a minute... this is not a sperm bank, right? |
|

You can easily recreate this idea at the roulette wheel, or by finding a bookee willing to take bets on flipping a coin. |
|
| |
So if you deposit say £100, your accounts gets credited by either £50 or £200. |
|
| |
That is, either you lose £50, or you gain £100. |
|
| |
If it's a random 50/50 probability then it's worth your while to just keep depositing endlessly. The probability would have to be 66/33 to make things even out. |

(Of course you'll have to alter the currency symbol appropriately depending which country you're in.) |

| |
what zen-tom said. as luck would have it, you'd end up losing by halves ***yes, my bank is half full*** |
|

[Wrongfellow] is right. (As I realized after posting this.) [+] for that. Corrected posting: |
|
| |
Each deposit you make to your bank account is randomly either halved or increased by three halves. Same for each withdrawal. |
|
| |
Or there's the option that random is not neccesarily 50/50. You can set the software to double 1/3 the time and halve 2/3 the time. |
|
| |
//either halved or increased by three halves// |
|
| |
So now you either lose £50, or gain £150. |
|
| |
To make it balance out with a 50% probability, you need to either lose £50 or gain £50 - that is, your deposit is either halved, or increased by 50% (3/2). |
|
| |
[Wrong] is right again. See corrected posting above. |
|

wrong is right again. Something tagline-ish about that. |

When I saw the title I thought it would be an idea for a
bank where you could deposit theoritical money. I was
pretty enthused by that notion until I realized we already
have one of those: the United States Treasury. |

Isn't this just a re-naming scheme for investment banking? |
