A lot of ppl (including me) bitched about their performance in last times (I'm skipping all the withdraw issues).
The performance didn't improve, a lot, but it did a bit... as well on the last downtime there has been a lot of comments saying they're being m/d/dos'ed, but I guess ppl who wrote that didn't know how to actually recognise such attack...
the servers were clearly accessible, just no frontend present (and api off msg).
So as much as they could still work on performance I'm pretty happy about this one:

I had small amount in btc so pretty much won't benefit a lot, but hey, I guess they're not that evil.
