I just started my nation and I have been buying infra at 10 levels ONLY.
I only buy infra if I have enough to buy 10 and I leave my remaining cash (to save up for more infra or to pay bills etc.)
I did this because I thought this is how you would be the most efficient since the price goes up each time you buy.
Since I started doing this I can afford 10 levels after bills every day. And lately I have been having extra cash after.
So am i doing this right? Or should i be spending every dime on infra buying 13.14 (est.) every day instead of just 10.
