6  Bitcoin / Hardware / About the BlackArrow Compensation for X1/X3 customers : Prospero X36 on: December 27, 2015, 01:46:18 PM
Anybody already read about the BlackArrow Compensation for X1/X3 customers ? : Prospero X36

http://www.blackarrowsoftware.com/store/index.php?dispatch=news.list
23-12-2015: http://www.blackarrowsoftware.com/store/compensation-available.html

--------------------------------

Black Arrow is happy to announce that has finished the design and testing for our latest miner: Prospero X36

Features:

    many times cheaper to manufacture than X3
    based on the 28nm Minion ASIC
    30-40% less power (around 0.6-0.7W/Ghash at the wall)
    3x smaller than X3
    3x lighter than X3
    10-20% faster than X3
    boots in less than 1 second
    more stable
    external PSU

Drawbacks:

    Louder than X3
    No LCD
    No GUI
    Designed with cost in mind therefore it is not very beautiful

Compensation for X1/X3 customers:

With the availability of this new miner we can start providing the promised compensation to most of our X3/X1 customers.

Unfortunately our current financial situation prevents us from building new miners free of charge therefore we cannot offer these miners for free. For this reason we are offering to almost all our X1/X3 customers more hashing power than we have promised initially but they must pay the manufacturing costs for the miners and we will offer the ASICs for free.

Our offer is to build X36 (2.2Thash) for each 1 Thash we have promised in compensation if the customer is paying the manufacturing cost of the miner.

Manufacturing cost to build a miner with 36 chips is 2500 RMB (US$390). They also require 2 x PSUs which cost 200RMB each (2 x US$31). As specified above this cost does not include ASICs cost which is paid by us for almost all customers to which we have promised compensation. Prospero X36 reaches 2.2 to 2.4 Thash at 0.6-0.7W/Ghash at the wall.

We will not be shipping this miner out of China. For foreign customers, in order to use this miner we will be hosting it in our data centre. The customer will have no configuration rights and we will mine towards the pool that we choose. At the moment it costs 19.21 RMB/day of hosting for 2.2 Thash. We will send to the customer periodically (around once or twice per month) the revenue in Bitcoins that remains after we pay the hosting fee. This fee includes maintenance of any failed miners so the customers does not need to worry about repairs. After the first 3 months (which are the warranty period we offer for these miners), we will charge a maintenance fee which is calculated by dividing the repair cost of failed miners between miner owners and their share.

Customers who wish to proceed with this compensation are invited to place the order on our website. In order to benefit of the free ASICs offer, please use the same email address that you have used to place your order for X3/X1 and write in the notes their order number for X3/X1 and the compensation expected.

This is not a preorder, the miners are in stock and will beging hashing within 2 working days.

Please note that at the moment these miners cannot be shipped out of China for these reasons:

    High domestic power fees makes it unprofitable to host the miner at home.
    The 5000 RPM fan generates loud noise which makes it unbearable to host it at home.
    We cannot provide warranty due to high shipping costs and customs fees.
    They require a CE/FC certification.

However, if you still want to have the miner at home or your own datacentre, please let us know. If there are enough customers to make CE/FC certification worthwhile, we will get it and ship the miners.

Legal notes:

    The compensation is being provided by Black Arrow voluntarily as a dedication to our loyal customers.  We are not obliged by our current or previous contract to provide it and we can withdraw this offer at any time, as we see fit, without a reason or any explanation.
    All orders are final, no refunds will be issued after we have sent the first mined coins to the customer.
    The hosting is provided by a 3rd party and they (not us) will be responsible of safekeeping of your miner.
    Power outages can happen from time to time and no compensation can be provided for it.
    This offer is not available to few customers that will be announced in private should they place the order with us.
    Our standard terms and conditions apply.


--------------------------------

Total costs for me (X3): US$ 894
Hosting: US$ 3,- /day

https://alloscomp.com/bitcoin/calculator :
difficulty: 93448670796
-> BTC 0.01237776 BTC /day = US$ 5,14
after next difficultychange: BTC 0.00973987 = US$ 4,05

US$ 8,10 (2 units) – US$ 6 (hosting) = US$ 2,10 profit /day
US$ 894 (2 units) / US$ 2,10 (profit/day) = break-even: 426 days = 61 weeks = 14,2 months
(if the next difficultychange and BTC-value remains)

calculation edited:
a unit costs more: 2 psu's needed for each unit
1 unit + 2 psu's = US$ 452
however: http://www.blackarrowsoftware.com/store/x36.html : US$ 447

7  Local / Nederlands (Dutch) / Homeshopping: Winklevoss ruimtereis betaald met bitcoins on: March 05, 2014, 09:22:57 PM
Winklevoss: ruimtereis betaald met bitcoins
Investeerders Cameron en Tyler Winklevoss, fameus vanwege hun claim op het Facebook-idee van Mark Zuckerberg, hebben een ruimtereis bij Richard Bransons Virgin Galactic afgerekend met bitcoins.
Dat meldt Reuters woensdagavond. De roeiende tweeling, tevens 'bitcoin-evangelisten' van het eerste uur, werken aan een fonds dat de handel in de digitale munt op de beurs mogelijk moet maken.
In hun blog vergelijken ze Bransons ruimtereis met de bitcoin-ontwikkelaars als de historische figuren die de wereld veranderen, zoals ook Marco Polo en Copernicus, stellen zij.
Virgin Galactic verkoopt de reizen voor $250.000 per stuk. Eerder betaalde een anonieme passagier van de ruimtevlucht uit Hawaï al met bitcoins.
Meerdere bedrijven laten zich in bitcoins betalen. Critici stellen dat de koers van de munt teveel schommelt om er serieus waarde tegenover te kunnen zetten. Recent werden bij een hackactie voor toen $375 miljoen aan bitcoins gestolen van het webplatform Mt. Govt.

8  Local / Nederlands (Dutch) / Escortservice neemt bitcoin aan on: January 22, 2014, 06:04:23 PM

Een Nederlands escortbureau accepteert als eerste in zijn bedrijfstak betaling in de digitale muntsoort bitcoin. Vooral het feit dat de transacties anoniem gebeuren, zou klanten erg aanspreken.
Volgens een woordvoerder van het bedrijf, 007 Escort, werd de betaalmogelijkheid ingevoerd nadat verschillende klanten de afgelopen maanden vroegen of ze in bitcoins konden betalen.
Bitcoins worden opgeslagen in een digitale portemonnee, die geïdentificeerd wordt met een code die bestaat uit een lange rij cijfers en letters. In principe is het niet bekend wie achter welke code zit, waardoor betalingen anoniem kunnen geschieden.
Dat is uiteraard aantrekkelijk voor mensen die van de diensten van een escortservice gebruik willen maken en liever niet hebben dat iemand anders erachter komt. "Daarnaast is het onder bitcoinbezitters gebruikelijk om bedrijven die de valuta accepteren, te steunen. Daar hopen we natuurlijk ook voordeel uit te trekken," aldus de woordvoerder.
Er zijn nog geen daadwerkelijke betalingen middels bitcoin gedaan, al is er wel enkele malen naar gevraagd. Deze 'dates' gingen echter niet door omdat de dame in kwestie niet beschikbaar was.
De seksindustrie is vlotter met het accepteren van bitcoin als geldig betaalmiddel dan de meeste andere bedrijfstakken. Zo is er in de Amerikaanse stad Portland al een stripclub waar met het digitale geld betaald kan worden en zijn er al pornosites waarop betaald kan worden met bitcoins.

Zouden het langetermijn-investeerders zijn?  Smiley
Proberen ze de bitcoins van nerds uit de zakken te kloppen?  Lips sealed
Heeft iemand al ervaring met een bitcoin-transactie in deze markt?  Cheesy

9  Other / Beginners & Help / Setting transaction-fee in MultiBit by editing multibit.properties on: December 29, 2013, 02:39:09 AM
I use MultiBit 0.5.16 (Windows)

In %appdat%\MultiBit\multibit.properties there are the options of setting the transaction-fee:
sendFee=0.001
previousSendFee=0.001

If I set these to 0.0001 will this overide the MultiBit-policy not being able to set the transaction-fee in the MultiBit-software?
I mean: will it use my setting (0.0001) for future transactions?

https://bitcointalk.org/index.php?topic=303407.0 does not give me a clear answer nor do any other topics I could find.

I know of the the new fee algorithm
+ 0.0001 BTC/ KB of transaction

Are the mentioned settings in multibit.properties simply ignored by MultiBit or are my new settings being used by MultiBit?
