Wow, when silver was at 49 I thought I had a lock. Not so sure at all now!
I am happy to pay you the 50btc each if it does not fall another 4.9$ :-)
I made a very good trade as I shortened massively between 45-49 $ and now it is 34.9$.
Silver is a great game, but you need the skill of cowboy Rodeo to play it.
