Play the game.... Or if you are scum, use Cheat Engine.
Find your money, put it in the box, run new scan. Go back to game, do stuff to get more money, go back to cheat engine, put in new number, run next scan, do it until you are left with 1 or 2 entries. Highlight both and click the red little arrow. Double click the numbers (while both are highlighted) and change them to your currency. You may need to get an extra dollar for the change to update. If it keeps ticking back (Dani probably doesn't know how to properly do anticheat) just tick the boxes next to the values on the very left and re-enter the numbers. There ya go.
