Yes, about 1.9 GB currently.

On average every 64 seconds a new block is created which yields 1.5 BLK (the block creator also gets fees of any transactions included in that block). The probability of creating a block is roughly equal to your stake weight (the number of confirmed blackcoins you owe which are currently not staking) divided by the presumed total number of online, non-staking blackcoins (which is shown in the graphical wallet). You can calculate your expected number of created blocks/blackcoins and compare it to the cost of keeping BlackCoin wallet online.

What development is going on?

Ryan Kennedy has been sentenced for 11 years due to three “rapes”. What about the Mintpal case?

I think there may be a good answer to do with this along the lines of "cold" or multisig staking but I'm no expert - if you ask it on the reddit you'll probably get a quicker answer: http://reddit.com/r/blackcoin

Edit: found this thread: https://www.reddit.com/r/blackcoin/comments/4gk008/boom_first_cold_staking_block/

You don't need to open up ports to your full node to stake so noone will be prodding the RPC to try and bypass credentials so the above solution is relatively safe as far as I can see so long as the computers themselves aren't compromised.

Also, due to recent work done on MultiBlack, I don't believe you even need to have a full node any more to stake either.

Best of all is big Vern(cryptsy case) getting out of country and stealing out blackcoins which were even not touched by hackers.

rat4 is, as ever, silently doing things in the background to improve the coin.

rat4 is the OP, he has always been like this. There are other active devs developing things around the coin. Generally speaking when something new happens, we find out about it when it's not vapourware unlike other coins.
