just farm as much energon as you can on the first day. cubes cost money and can't really be farmed on a raid event. the most you can do is break even on them. energon on the other hand are free for farming on day 1 and a little bit on day 2. so to me it's better to go for it early and burn energon than burn cubes later on as cubes cost money and energon do not. that being said, you still have to save a bunch of energon for the last couple of days. mismanaging that will cost you a lot since if you actually do need to buy energon...it costs a lot more than cubes.
