@blocktrades, I am sure you are already aware of the concept for accessing frozen funds on Steem as pointed out by @inertia - https://www.waivio.com/@inertia/theory-how-to-side-step-soft-consensus
And while I am using Bittrex for now, I would love to see Blocktrades resuming Steem to HIVE conversions soon. Thank you for your hard work, patience and resolve.
Even if it works, I don't think an exchange will be able to operate on 1 transfer per day, if that.
If @blocktrades account is frozen on Steem, maybe accounts (created via Blocktrades) should change their recovery addresses?
