I believe they are okay. The usual 3-5 days I think. But true, the design is a bit archaic for today's standards.
The reality is less fancy sites are more trustable. Just for an example, I'm showing u this site => https://oilrigcontractors.com ...How well designed it is ...is not it ? But its a SCAM site. Even if u look at Google.com ...they are blank. But they are great in their business. From my little experience in the web I have seen this is true at different times. Less fancy sites are more trustworthy.
this may or may not be true in general. in the case of btc-e, though, i agree. ugly/archaic looking interface, but the best exchange around.
It's okay for us who don't care about how it looks, but what about new adopters who come in and say: what is this geocities crap?
It's ranging with deep web websites.
