Sometimes people have trouble stopping themselves gambling. Sometimes those same people want to help bankroll Just-Dice.
For those people I allow them to set up an "invest lock". They specify the terms, and I hold their funds in the bankroll until those terms are met.
Example terms would be "I want it locked until 2 weeks from now" or "I want it locked until CLAM trades over 0.01 or under 0.004".
When you set those terms, I take them seriously. If you ask for the lock to be released before your terms are met, I will refuse. If you keep asking, I won't let you use the lock again in the future.
Neither "come on, it's nearly time" nor "your girlfriend is a bitch" are valid reasons to release invest locks early.
