Minimum IP for big crunch

[UDcc123]

Math isn't my strong suit. What do I set Big Crunch automation to (minimum) to get the fastest challenge clears?

[Hypertext Eye]

for challenges specifically? 0

Having the big crunch autobuyer on at all should cause it to crunch as soon as the interval comes up where it can, even if the amount is higher than the minimum.

The actual answer to the question is to use the "crunch at X IP" option (if you've unlocked options) and choose 0.
