Daily Casts: gains 8 credits in four turns
Data Folding: gains 8 credits in eight turns. Turns off when you start installing programs, unless you also spend credits and cards increasing your memory well beyond what you need for your rig.
Basically, don't play this card instead of Daily Casts. Probably don't play it in addition to Daily Casts unless you are playing a deck that will stall the game out incredibly long AND has excess MU (MemStrips or some sort of Ekomind combo)
