Thank you for aswering and taking the time to get things clear. I even learned from it.
The question I came here for was to ask when the bittrex-wallet would be open for deposite.
To other forum-members: dont be shy to answer too.

If you're talking about SILK Bittrex-wallet: it's blocked for now (because of the mintpal account issue) and unless you had your SILK in before the block you won't be able to deposit more, but still your SILK is there and will be swapped 1:1 to SLK and on 17th you'll have the new coins ready
If you're talking about SLK Bittrex-wallet: it will be open on 17th so will the new market SLK-BTC
If you have more coins and wish to get them out of POLO use weaver wallet (after you register at silknetwork) or desktop wallet
correct me if I'm wrong
