The bittrex told me that HMY hasn't been delisted yet.
It was in Blocked status caused the slow blocks found.
https://bittrex.com/Status

So if we keep our wallet open, we can go on trading hmy in Bittrex again.
The bittrex checks the new block every 30 mins.

Hope that someone can lead hmy project again.

I'll go on keep the block chain(http://hmy.blockex.info) open smoothly.

Best wishes.
