Investing with Interest Free student loan?

[NOCASH]

Hi,

i can get around 2000$ interest free loan from ASB and another 2000$ from kiwibank interest free also, but have to pay total of 2+2=$4 a month in admin fees.
Should i apply for it and spend that 4000$ on stocks or FX?

deposting the 4000$ in a online saving account will only make a profit of 3$ each month after deducting 4$

Bonus bonds? try my luck but then i have the chance of winning nothing and cough up $4 expense each month.

FX.

Even with 4k the commission kills with stocks. And with FX you are less likely to blow it all with a gap down.

I think its better to invest when you have money leftover.
