Infinite credit dupe trick patch [100% working] [June 2025] [No download] [Link in video description] (#91455)

So it turns out the spacebet app verifies that the user has the money to
make a bet only if they already have an active bet and they're
increasing the amount of money it is, with a fresh bet this is never
checked. This means someone can bet 10k credits on an option, it will
place the bet with no regard for their account balance, then they can
set their bet back to zero and the app will happily refund them 10k. Now
they have 10k. They can do this as fast as they can type the numbers
