The reason for the delay can only be multiple claims for the same wallet: we need to sort things out.
People with wallets under 50 BTC and no multiple claims on their wallets have been paid out.

Cool shirt! Please consider listing @ www.coingig.com as well.

Very interesting address, and very interesting closure.
The closure is fairly large (around 393 addresses).

The earliest TX into the closure is a block mined on 2009-01-13.

(Interestingly, that is earlier than the first TX into the address given:
one of the nice property of the closure tool is that you can sort of travel
back in time.)

After that there are a whole bunch of BTC50 TX paying into the
closure (likely mining revenue, didn't bother to check that they
were actual block mined type tx). The owner is definitely a very
early miner.

The balance for the closure peaks at BTC95k around mid-2011.

Either the owner decided to cash out at that time, or he decided to
spread his coins to addresses outside of the closure to be less "visible"

Transactions in or out of the closure are nicely spread over the range [2009-today].

Latest TX in or out of the closure is from 2013-04-04 which seems to
indicate that our miner is still alive and well

To get a vague idea of where the money went, I ran a taint analysis of TX
paying out of the closure.

Because of how early this closure starts, it almost taints *every* TX in the
chain, so I chose to only keep TX whose output is tainted by more than 75%
by the closure.

That's about 2028 transactions, involving about 5000 addresses. I computed
the balance for all of these, and ... the outcome is very interesting  

现在testnet中遇到了一个问题，我挖出来的全部都是immature状态，不知道怎么才能变成可用的btc。
