I don't think we will see 500 ever again 
I'm sticking with my plan with orders below 500. I'll get myself a few ounces of silver if this wont get filled
My problem for considering 500 as a bottom is that there are almost 16 millions of active usd swaps at bitfinex and it feels like they are just waiting to get squeezed sooner or later
Do you really think it is likely that Bitfinex could bring down the whole market with just 16 million? I dont think its likely to crash on its own, there is plenty of arbitrage support.
