Unfortunately yes. If everyone do something like that I would have no money to investment and my system will be little "frozen". Why not wait 720 hours and get 130%?
What you mean by "frozen"?

Because you
might run away with investor funds before the timer ends.

Do you accept escrow?
I'll send 1 BTC to an escrow and after a month, you will pay me 1.3 BTC and escrow will release the fund to you.
