After taking a technology action, gain $2000/phase.
Receive $1000/phase after trading...
Immediately take $5000/phase from the bank.
My question is:
Does x/phase mean once for Phase so max 3 uses?
There is no limit to the number of uses, save for the studio. The studio, once you flip it over, you get $5000 * phase #, so if in second phase you get 10000.
