Wall Observer BTC/USD - Bitcoin price movement tracking & discussion

[cyclotronmajesty]

Is that staggered bid wall formation on Bitfinex relatively new or did I just not notice it before?

Looks new to me. Wonder what that is about... I think there are tricksters on both sides working to keep the price down. But I'm not sure how that staggered buy wall helps them.

BTC Closing Down
BTC Guild is Closing Down
BTC Guild will be shutting down its mining servers on June 30th, 2015 at 23:59 UTC. Users will still be able to log in and retrieve their history (CSV exports on the settings page) and request withdrawals until September 30, 2015..



Why is BTC Guild Shutting Down?
This is the second time BTC Guild has announced closure, but this time the decision will not be reversed. The reasons have not changed much since the original announcement.

As mining has become more centralized, BTC Guild has continuously shrunk in proportion to the network, now being less than 3% of the network hash rate. The costs of running the pool have not changed, and the amount of funds at risk in the event of a compromise is significantly higher than what the pool could ever recover from. When the pool was 20-30% of the network, the amount of funds at risk was slightly higher, but the ability for the pool to recover from that loss was present. At 3% of the network, the pool would not be able to recover from such a loss..

Additionally, the NYDFS BitLicense regulations have now become finalized, and the final regulations have enough gray area that BTC Guild is at risk. The fact that BTC Guild is not in New York does not matter, since it would be doing business with New York residents while they are physically in New York. This fact makes it possible for New York to attempt to claim jurisdiction to enforce regulations. Whether or not BTC Guild could win in defense of such an attempt is irrelevant, since the cost of defending the pool would be greater than any income the pool is expected to generate going forward.

Finally, I have been growing concerned for some time now about attempts to defraud pools. The pool's luck has been on a decline for over a year. The luck on a few other pools has also shown a negative trend. While it is not impossible that it's a coincidence, this is something I have been constantly made aware of and am helpless against. There is no way to know whether it's just bad luck, a small bug in older miners (BTC Guild probably has the highest percentage of first/second generation ASICs) resulting in a few % of block-solving shares to disappear, or a large pool trying to hurt the competition (many of the largest pools have large private mining operations now). It would only take a fraction (1 PH/s or less could do it) to cause significant harm to a competing pool, and that activity could be masked by proxies and multiple accounts to be impossible to catch.



PPLNS Blocks and Final Withdrawals
Users will be able to keep mining up until the servers turn off at end of day June 30th. Since PPLNS is a backwards paying system, the very last shares submitted are unlikely to receive any blocks unless a block is found at the last second.

The PPLNS shift length will be steadily reduced starting June 16th. This means that more shifts will likely end with 0 blocks, but shifts that find blocks will receive a larger amount than they would have previously. It is not recommended that users wait until the last minute to change pools.

The minimum withdrawal for a manual withdrawal will be reduced to 0.0001, and will not require a transaction fee to be paid in order to request the withdrawal.



Not For Sale
In the previous closure announcement, one reason it was cancelled was due to offers to purchase/take over the pool. This never happened because of personal attachment to the project and concern over user privacy and security.

The risk of users being cheated or stolen from as a result of transferring pool ownership is not something I am willing to accept. This is part of the reason the pool is closing in the first place: Risk of users losing funds because the pool would not be able to cover losses in the event of compromise.

I will not be entertaining offers on purchasing the pool this time around. There is no (reasonable) price the pool would be sold for.



Recommended Pools
The following pools are personally recommended for users to consider moving to:
BitMinter - long standing pool with good reputation
Eligius - long standing pool with good reputation
Kano CK Pool - cgminer developers
P2Pool (decentralized pool)



Thank you to all the users and the Bitcoin community for making BTC Guild a success for the last four years. It has been hard to finally make this call a second time with the determination to not reverse the decision. You will still be able to find me around the Bitcoin Talk forums (outside of the Pools subsection for once), and on IRC in #btcguild (and probably #bitcoin once the pool winds down).

To bad to bad them is the reality at this time. Pool helped move BTC into ASIC territory with the advent of stratum integration testing.

Ahhh,.. fudge!

Now I have to change the backup pool for all my miners. There goes the weekend.

<btcguild shutdown notice>

to bad them is the reality at this time. Pool helped move BTC into ASIC territory with the advent of stratum integration testing.

Also worth mentioning that the pool operator eleuthria played an instrumental role in resolving the fork back in the day. It was the first pool I ever mined at and I will shed a little tear when they shut down. Only silver lining is that hopefully bitminter's share will go up.

Flight duration please and can I have my nutella sandwiches with me

Luke-Jr must be happy

is there a story behind this? Eligius is for the block limit increase and isn't including TX's to press the issue?

He stated that a blocksize decrease would be beneficial and settlement times of +24hrs for confirmations is healthy.

Since he created Eligius I am imagine that he is quite pleased it managed to pull a .24kb block.
