It keeps popping up: invested coins count as "balance" for faucet purposes. It protects agains the following: open investment (balance is zero) & claim faucet & close investment & open investment (balance is zero again) & claim faucet.... This way you could systematically claim faucet available to you.
I keep thinking how to solve this. I think it would be really cool to allow investors to use the faucet to play a bit. Just judging from how the faucet is currently being used and how creative some players are finding ways to empty it, the simplest solution might not be the best one.
If you have any ideas - tell me!
Option 1 - Lock investments for X hours - usually it's 12-24 on other sites.
Option 2 - add a divest fee that changes with time - for example 5% in 24 hours, 2.5% in 7 days, 0% in 21 days
