There is too much risk from both end but of course this may be a good idea as a hunter I don't need to wait for couple of months. In your end, where's the assurance that the tokens will transferred to you as you know that payment address will not be changed or it is hard to change it. And in our end,  how it works I mean how many days until we get the exchange? Can we sell or exchange the stakes even the campaign is not yet over?

-edit so it is only for kamagames?
