Well after talking this over with family tonight,
I have come to the conclusion that it is not a bad investment after all.
However there should be no rush to buy up the 500 units at once, instead a better way to go about it would be to gradually acquire them over the next 3 - 5 years as the game further develops and a clearer direction to MAs thinking and doing unfolds.
This way a line of credit will not be needed on the house to purchase them, instead I will get them from my RL income.
For now, back to playing for fun
