Saw this thread so I decided to play here for a bit. Dropped a few mbtc playing around.
Went to withdraw and I saw your fees are a bit on the high side. Just my opinion on that.

And then...my fans started to spool up. And saw my browser was taking up 1 entire cpu core.
Looks like something on your site is not optimized.
No idea what, might want to poke around to see what it is.
