What would you do if it was you?

This is just a dream. Ok. You have 1.25 million. Now you have to invest it 45 days or pay capital gains. Capital gain tax rite now is 33%. That comes to 412,500. If you don't invest. So you'll give that to tax man on the 46 day. Do you invest and roll on worse case, business fails or do you let the tax man have his piece and hide the rest. What would you do. No guarantee business will or won't fail.
