You can choose the renting rate by yourself, BUT most probably not all of your tokens will be rented out at that rate, and part of them will stay unrented. This is because not many people are willing to rent at high price (in fact rate depends on the qty of miners, and most people who rent now are old GW customers with big qty of miners).  Initially i tried to rent out at higher price but only part was hiring.  So i decided to lower the rate, and now all tokens are rented out.
