I finally got a chance to look into this. At first it puzzled me. Who sends so many coins to my 'online storage' over and over again? Mostly the only two wallets that send coins there are the JD cold wallet (which is a single address) and the JD hot wallet.

1JzHCtJTG4LoPP2ks7mzPw5VwSmMpVvHpL isn't in the JD hot wallet:

Code:

$ bitcoind validateaddress 1JzHCtJTG4LoPP2ks7mzPw5VwSmMpVvHpL
{
    "isvalid" : true,
    "address" : "1JzHCtJTG4LoPP2ks7mzPw5VwSmMpVvHpL",
    "ismine" : false
}

Then it struck me. JD accepts deposits to inputs.io. When the inputs.io account gets "too big", I send the whole BTC part of the balance to either the hot wallet or the online storage, depending on how much is in the hot wallet.

That's what you're seeing here. 1JzHCtJTG4LoPP2ks7mzPw5VwSmMpVvHpL is an address in the inputs.io hot wallet, not JD.

So I figure all you've discovered is that both JD and the DDoS-er have used inputs.io...

Here's a screenshot of the inputs.io 'details' popup for the first transaction you link to - you can see the txid and amount match:

I guess the next step, should you want to pursue this, would be to contact inputs.io and see if they're interested in tracking this further.

Edit: as for the payments from the hot wallet to that address, they were all made by the same player. He had the unusual play pattern of depositing to the site using inputs.io, and very soon after winning, would withdraw, always to the same address. It turns out that address was his inputs.io deposit address.

None of this connects the player with the DDoS address of course. inputs.io is a shared wallet. Coins I send to it go into a big pool, and will be given to a random person in the future when they withdraw. All we can conclude from this is that Just-Dice, the Just-Dice player, and the DDoS guy all use inputs.io.
