It is as simple as opening the box. You will not always get YoCash. It is random. Sometimes you will get a prize, and other times you will get either YoCash or YoCoins. There is no way to predict a gift, or to force it to be YoCash.
To open the box, go into decoration mode. Place the box in your room like you would furniture. Save the room, and then click on the box. You will be notified what prize the mystery box contained.
You can answer survey and it will give you at least 1 or 2; install yoville tool bar and that will give you 12 yocash; open cottage box and it will probably give you 2 yocash.
You can't trade yocash on yoville in trade, if someone did, you have got scammed(:
75 yocash :)
There is no longer the earn yocash for free. If you want to pay for yocash in a different way. While playing yoville, click the "EARN YOCASH".
There is no such thing as yoville dollars, just yocash & yocoins
i got hacked by 200,000 in yoville and 650 yocash
You have to pay money to get it.

They're mystery chests, so you never know until you open it. It's either a gift, coins, or yocash.
buy yocash with credit card or just go to event and find yocash dealer or people who are selling yocash stuff for coins
there is no trex in a mystery box
you cannot trade yocash but you can find a yocash dealer that will buy yocash items and sell to you for coins, you should negotiate before the trade.
