Most people have enough spare keys that we should have a private invite only exchange but you know bad faith actors would make a mess of things as without an escrow who can verify the keys it is nothing but a blind honour system. But all the same if there are keys someone wants to exchange I would be open to it.
I want to crowdfund one of my games and have it at, like, $10,000 for the goal. I want to leave St. Louis for a week for a change and get a nice, kick-ass vacat-- Develop a nice kick-ass sequel to Super Push Adventure.
$10000 feels a bit on the low side, but I have no idea what the game is and you are likely afraid that the game wouldn't get funded at all which is understandable. Not being able to cover your expenses though is even worse as you have to take time off to bring in other income etc or release early which would piss everyone off without a doubt.
I would aim higher than my expected expenses and if it can't get funded for even a small bump for safety then there wasn't a market anyway. (Unless you already taken account of this).
However there is a way you can have your cake and eat it too via stretch goals. If you are sure that you are going to get funded for the initial amount add in features that don't take too much off course to bring in more money which would help ensure success assuming the game doesn't suck.
