Users wishing to hide their orders can do so by applying the "Hide this order" attribute to their order and completely hide it from the market.
The Hidden order type is a simple solution to:
1. Maintain anonymity in the market when trying to buy or sell large amounts of bitcoin
2. Avoid competition with bots
3. Ensure that other users' 'Maker or Cancel' orders will still be matched with your Hidden Order.
If matched, Hidden Orders always pay the Taker Fee.
