Enable lower amounts of Coins being withdrawn in the last months of Coins as a gamble mechanism
As user "Tim" mentioned: amounts lower than 7500 coins cannot be withdrawn currently as per WarLight's coin withdrawal rules.
While this was fine for most of WL's life, right now this is quite bad. Someone who has accumulated a good value but lower than 7500 due to spending/partially withdrawing will have permanently lost a pretty steep amount of money due to the withdrawal limitation.
The suggestion: Lower the withdrawal amount to be something pretty small, such as 500 coins. Very rarely do people who did not actually invest in Coins get to that number (they'd have to quintuple their starting value, which is quite an impressive feat), so actual losses would be relatively minimized.
The alternative: Use this if allowing coin withdrawal would be too expensive or troublesome. Reward players who have coins when the coin system is changed. Give them a bonus, perhaps allow them to unlock a color for free, or small periods of memberships. This'd make coin investments who didn't quite make it to 75$ not be wasted.
Coins can no longer be withdrawn.
