I'd buy 50,000 wishes
I will gladly sell you 50,000 wishes for the fee of .001 BTC. Now I am not guaranteeing that any of these wishes are going to be granted in any way, I am just willing to sell them to you!!
On my own side, I would really like to buy a house. I have a family of 6 in a 3 bedroom home that is on the small side. No one has any private space except for me and my wife, in our bedroom. So I would really like to buy a house to call my home!! If anyone would like to grant me this wish, please transfer 2,500 BTC to my BTC address in my profile!! (Nice thought)
