Thanks owlhooter, that was what I was looking for.  Now I have this:

STATEMENT FROM SUCHPOOL.PW ABOUT DATABASES ISSUES ON 2014-04-19

Dear users,

Today we have had a quite noticeable interruption in our services.

Please note that our Quebecoin pool was noticeably less affected than others since the database was much smaller, and somehow has been easier to recover than others.

Please take a look at the statement we posted online, detailing the situation and what has been done to ensure the smallest loss possible.

If you have any questions, you may contact us at admin@suchpool.pw (Make sure to mention which pool it is about, your username, your deposit address) We will verify and credit what has to be credited if applicable.

Thanks for mining with us!

Thanks a lot owl. We try to do our best, it is just sad some users just don't understand. No coins are "lost" because our wallets are on separate servers and weren't affected at all!

To be honest, I never expected we would pull this off and save the most part of the last 36 hours of data. All the credit goes to CoinFinder who was able to recover most of the corrupted tables!

I am new to Bittrex exchange and was wondering if someone could tell me what is the minimum amount of BTC needed for a BTC-QBC trade.  Then what is the minimum amount allowed for a withdrawal of QBC.

Minimum trade at the moment is 1 QBC, how many BTC depends on the trade rate, there is no minimun withdraw amount but take in mind that is a 0.001 QBC fee on that withdraw.

I asked about it in their IRC channel and received this response

And divided by 100.

Everyone with syncing problems, it's really easy. If you've never done it before, just create a text file with the add nodes from the first post, rename it to .conf from .txt and put it in the app data folder and restart your client.

Guys from OkayPool, I've got 2 auto-payouts of 10 QBC with different TxFee:
79727    2014-04-19 18:51:24    TXFee    Confirmed    QVR......hE9       n/a    0.00100000
62677    2014-04-19 15:48:02    TXFee    Confirmed    QVR......hE9       n/a    0.10000000

100 times difference is quite a lot. And your promise is 0.001 for auto-payout. Please explain. Refund is welcome.
Thank you.
