For gods sake. Can we all just acknowledge that the exchange is currently in Beta testing (which you really should understand BEFORE throwing money at an exchange), and things take longer/sometimes do not work as intended.

With regards to deposit times, the COSS team keep all coins in cold storage, so yes, it takes a while. They have clearly stated that at the present moment they prioritise safety and security over your arbitrage potential. If you need further information it is clearly stated in the FAQs.

Please understand this BEFORE you use the site. If you can't handle it, come back and buy COSS at 10$ with its flashy new UI and upgraded engine. If you believe in the team and the vision, this is just a part of early adoption. Growing pains are natural. It's buggy, it's slow, it's in Beta.
