Remember you only ever Lose value if you Sell 
If you never Sell the price on the exchange is completely irrelevant and you never lost anything to begin with just a percieved worth at that moment in time is all it is..... Hold on for better days price only matters when you sell or buy and if you stand to lose just SAY NO there's plenty of other days ahead don't let it get to you and PANIC sell and make someone else richer.....

He's not looking to speculate, he wants to use it as currency as it is intended.
