I agree with other commenters. The investor didn't give you the money to invest in, they gave it to you to invest in your business.

In Australia we have easy access to high interest savings accounts that can be attached to a regular savings account. So money you put in this account can't be accessed by an atm or used for daily transactions but you can put it into your main savings account instantly when ever you want. But for every day it is in this high savings account you will earn 5% interest.

Ask the angel investor they would also probably have some great ideas.

But focus on investing that money in your business. You have a burn rate of about $5k-$9k would increasing that burn rate by investing more into your business (people, sales, marketing, etc) help you reduce that burn rate quicker?

Anyway I have no idea what business you are in, but use it to invest in your business, that is what is was given to you for.

As someone currently maintaining bank accounts on both sides of the Pacific, interest is way higher in Australia than in the US right now. You can easily get 6% or even more in Australia with money at call, whereas circa 1% seems to be the norm in the US.

For me this means a change of strategy: I'd bother with the additional bank account to get six percent, but not to get one percent.

Exposing yourself to exchange rate risk isn't worth it in this case
