Can someone clarify, Escrow funds will stay with bittrex and market will stay closed for a fixed 72 hours since ICO ended, OR is there a chance that Bittrex verifies working wallet/explorer earlier so that would lead to market being released in say 48 hours?
Only Bittrex can answer this. I presume that it will be fixed 72 hours, but I don't see what may change during that time. You can always ask them directly via
support@bittrex.com and generously post their reply here.
