120 days passed from the day Poloniex stole 1800 BTC from it's customers to cover it's losses incurred in CLAM price crashes caused directly by it's incompetence and poor management. They announced that they are "committed to making lenders whole, come hell or high water" but I received only one 10% repayment 112 days ago and not a single satoshi after that. Beware of Poloniex!

Did you compare your earnings with whattomine.com calculations? Me and my friend was getting half of this what we should. I checked some random addressess form miners list and hashrates did not correspond to rewards also.

Is there any decent Zclassic mining pool that doesn't steal half of your earnings like supernova or miningspeed do?

Thanks for keeping the list up to date!

Will China's regulations have influence for Hong Kong based exchanges?

Armory is doing the same thing - imported private key adds to wallet uncompressed bitcoin address.
So what is the whole thing about? Can I relate offline wallet with compressed bitcoin address? Can I sign transaction offline having only paper wallet data?

I want to spend bitcoins from paper wallet without exposing my private key to online computer.  I thought it's pretty easy task using for example Electrum offline signing. But in practice I can't sign transaction because offline wallet restored from private key is related to uncompressed address and online wallet to compressed one.

Which clients are you using and how are you doing this?

Is there any client providing such a possibility? Eventually is there any clear guide how to do it manually?

Yes, but my balance is 0 in uncompressed address and I need to spend funds from compressed one. I can't import address on offline computer this way as you pointed. Transactions created on online wallet are treated as unrelated to offline one. So how can I relate my offline wallet with compressed address?

Thanks, I've gone a little bit further in the process but another problem occurred. I can't sign transaction because offline wallet restored from private key is related to uncompressed address but transaction with compressed. What can I do about it?

Following guide http://docs.electrum.org/en/latest/coldstorage.html I intended to spend bitcoins from paper wallet signing transaction on offline machine. So I created Electrum wallet using given private key. However button Wallet -> Master Public Keys is grey, so I can't obtain PubKey and create a watching-only version on online machine. What is the case?

What kind of Public Key is actually needed? I obtained uncompressed -130 characters and compresed -66 characters from bitaddress.org (offline) but it won't go through.

Electrum-2.9.2
Ubuntu-16.04.2

Any progress in this case?
