Coinbase: when I purchased, it said the coins are in my wallet "instantly". When I read your message about missing out due to delays, I did a withdrawal from coinbase to my local wallet and it came through in a few seconds.

What did you mean by missing out?


Cex.io fell in the same basket as Kraken.com in reviews: people seem to be coming to b$tch about them on bitcoin talk in order to get their support tickets resolved and both have reduced their functionalities to reduce the work load. Didn't seem too shiny.
