I'm looking randomly at Binance Uganda. The request was sent 11:22pm and responded 2:00am. That's about 2.5 hours. In the table that's rounded up as 1 day.<p>ArgenBTC, if I understand the screenshots correct, never answered and that's logged as 0 days. "A response time of 0 means that we received a reply the same day."<p>Independent Reserve answered after 25 minutes, that's also logged at 0 days.<p>With these examples I'm not sure I trust the calculation of the average. Maybe listing it in hours and putting those who never answered in a separate list makes sense.<p>(I don't hold bitcoin and don't know any of those companies).
