So im in the process of looking for a new place for my new wife and I, we found a place and need to come up with a deposit. I really really don't want to sell my holdings. Can some one explain how this works with the markets always jumping down and up. I remember reading that you need to put up 150% then you receive there tokens that you can cash out. But what if i do it and the price tanks or launches. What am i paying back?
