Come mi dimostri che una banconota da € 50 nel tuo portafoglio è la tua e non è la mia ?
solo perché è al portatore.
Beh, anche il bitcoin e' chiaramente al portatore, chi ha le chiavi e' il proprietario, perche' e' l'unico che puo' disporne (a meno di indirizzi multisig controllati da soggetti diversi). E da qui nasce il problema di dichiarare quanti se ne posseggono nel quadro RW, nel caso se ne possegga quantita' ingenti, perche' sarebbe come dichiarare che in casa si tiene un sacchetto di monete d'oro o una somma ingente in contanti. |

Bitcoin / Group buys / Re: [lee group]1150$! The group buy of hosted bitmain S7 @4.73T online on 27th Jan!!

The main reason i want to go via this proxy is that i have one central web interface (the stratum-proxy has a decent one) under my control where i can tell Lee Team once to point my miners to the proxy as first pool and change all pool priorities, worker settings and more myself after that. It's really a win-win.
mxnsch, if your proxy is outside of China you'll end up against the Great Firewall of China and your miners will not be able to reach it (stably at least). So you'll need to have a pool inside China at least as a backup. I'm mining with Lee since the beginning of 2014 and in the end I was forced to use Chinese pools to have reliable mining (I was using Slush's proxy running in a datacenter in Europe).

I know that exchanging or "core" charges may complicate a project that aims to be very simplistic and straight forward. It may be possible to have a "complete" miner and a blade for the DIY guy but that will depend a lot on the final design from Sidehack.
Having stackable boards requiring just a raspi to run or boards you can put in a wooden frame like in the good old days of GPUs would be a plus, IMHO. Or something like the m/h boards of the first bitfury rigs; maybe they can run with just a fan blowing on them. spiccioli |

Economy / Computer hardware / Re: WTS - 25 Antminer S5's hosted (will possibly sell without hosting)
|
on: January 10, 2016, 09:40:47 PM

I appreciate the interest from people, here are a few comments to clarify.
I do not wish to break up the 25 units into smaller batches.
At current difficulty and hosting fees, the miners generate approximately $1300 USD profit per month. That is calculated using 1155*25= 28.875 Th with fees being $0.065/kWh
Bottom dollar on the 25 units with hosting - $7000 USD in BTC
Bottom dollar without hosting is $5750 USD plus shipping costs.
Thanks
Hi kilo17, when does the prepaid hosting end? Regards spiccioli |

Other / MultiBit / Re: Multibit classic, error in protobuf
|

Hi Jim, Thanks for your answer, I'm on 0.5.19 and I've been using it since it came out. Before it I was using 0.5.18 and that wallet has been in use since a couple of years ago with daily movements. So why is it still using the old format? Isn't it enough to open it with 0.5.19 to have it converted to the new format? Does its size, 68 megabytes, pose any problem in handling it? Thanks spiccioli The very early versions of MultiBit (up to 2012 I think) used a different format for the wallet (Java serialisation rather than protobuf).
Only the protobuf version is supported now.
For a while the old versions were read in and converted to protobuf when written out so that users that updated via each version would not have noticed.
The old versions are still available on the multibit.org website if you have deleted the older version you can reinstall it.
Probably the best thing to do is:
+ using the old version of MultiBit Classic, empty the wallet to somewhere else.
+ install the latest version of Classic (or try out MultiBit HD) and create a new wallet.
Very old versions of MultiBit Classic don't even connect to the Bitcoin network any more (as things have changed over the years). In this case then:
+ Export your private keys.
+ Use the most recent versio of Classic and import them. Or import them to blockchain.info using the help article on how to do this.

It had no problems a few days ago to update the same wallet and send some, wallet size is 68711158 before starting MB. What can I do now? Even the rolling backup gives the same error and it selects an old backup from beginning of this year which, apart from requiring a few days to completely sync, makes me really nervous, what if I can't load this wallet anymore?

Bitcoin / Group buys / Re: [OPEN] [Group Buy + Group Hosting] 3.5TH/s Avalon6 + Platinum PSUs!

Well then, the deadline's come and gone and we didn't get enough interest. Too bad, I was looking forward to picking up a few Avalon6 units for myself! Perhaps we can try again with a later batch.
Those who reserved units please PM me with the address you would like your deposits refunded to.
It's a pity. Hosting fees are really good and even PSU lease is an idea which should be tested, but units are way overpriced, much more so with BTC at current level. At 450 USD per BTC it would have been very different (well, if Avalon does not increase their price at 2000 USD each). spiccioli |

armedmilitia,
you said we have 10% discount on units from site's price.
They're priced at 13900,00 USD per 10 units, so their price should be around 1250,00 each at least from 10 units, I see them at 1300-1320 instead.
What am I missing?
Regards.
spiccioli
Found it  Controllers (Rpi aren't included). spiccioli Hmm, the price on the site was previously 14.4K, they must have changed it recently. But yes, we get the advantage of pi's. Ah, ok, so now we're at 1251,00 USD plus as much RPis as we need and they're selling them at 75 USD each, so maybe we can source them elsewhere for less. spiccioli |
