Ruse to get more money...

I loved high rise before the new update, but now its freakin horrible. If you want to buy an object from another player, you need to go to the vault and buy gold nuggets or bars... Which cost more than they are worth. Then you can trade; but if the item is a block, wallpaper and other small items or furniture which no one buys for more than 5 gold, you have to use nuggets because they are normally priced at around 2-3 gold by other users. If you want to buy a block that is 3 gold, you go to the vault and pay 6 gold for 3 gold nuggets (the trading currency) to trade the block for. Those three gold nuggets are only worth 3 gold, but you bought them for 6 gold.
Its a horrible idea. Gold is hard enough to come across without buying it. Highrise is just trying to maximize revenue, but are ruining the gaming fun and uniqueness in the process.
