To maximize your money gain you’re either going to need to add more tiers, you have already sold out 3. The new tiers need to go for at least 55 - 100$ or raise the maximum pledges for certain tiers, like the 90 and 75$ tier.
I’m suggesting this as when you get to the 60$ tier, the next available tier is 200$, now this is going to cause some problems with people, and most who were going to pledge a higher amount than 60$ are probably going to save some money and only pledge 60$. My friend wanted to donate 90$ when he got paid, but now he is only going to donate 60$ and save some money.
The new tiers could have a cap on them and give you like one extra key for the game like a 100$ tier that is just like the 90$ tier but gives you a beta key or something.
Can I suggest something happens with this stuff before youtubers get a hold of it?
If it is too late to edit tiers and pledges on Indiegogo, then disregard this post.
