So you are saying that they would return the BTC and still deliver the product?
Not continuing the project is the same as cancelling it as I see it. So my facts are straight.

There is not official minimum amount. However, no less than 1000 BTC would be required to develop this platform and to build our sales, business development and marketing team. This is the minimum amount required to have the capabilities required to make this project a success. In the unlikely scenario that we did not exceed this amount, we would refund all investors. I am confident that we will exceed this amount.
