Hmm not really. All depends of how much you pvp and farm. I started O.D. FARM as test for the Base. Even enhancing the base I was able to keep 1,000,000 save and progressing. You can save gold without advance your mechs if you feel that you can hold a bit to balance budget. Not difficult but require time and timing to farm no losing gold opportunity to cash in during the day. Now I have phone, comp at work, comp at home etc so when I can sneak myself resting a bit I can click and drain a bit energy bars.
