1  Economy / Goods / [FOR SALE] Ledger Nano S, new, sealed, available NOW in EU on: January 17, 2018, 12:59:18 PM
Hello,
I own two Ledger Nano S, new and sealed. Wallets are in Italy, and I can ship in all the EU with no custom fees.

My asking price is 170€ and I can accept most payment methods: PayPal, bank transfer, BTC (can accept escrow, but at your expense!)
Ledger factories are stopped until 22 March so this is almost the only way to get a Ledger Nano S now without purchasing second hands - that's also why the price is higher than official.

Here are two photos, I can provide more on request but it's just a sealed box Cheesy

2  Local / Beni / [VENDO] Ledger Nano S, disponibile già in Italia, sigillato! on: January 17, 2018, 12:46:28 PM
Vendo Ledger Nano S, ancora sigillato, ne ho solo due disponibili.

I due wallet sono nuovi e ancora sigillati, accetto pagamento con qualsiasi metodo: PayPal, bonifico, BTC (con escrow a carico dell'acquirente).

Il prezzo è di 170€, è praticamente impossibile trovarne di nuovi ora, siccome la produzione di Ledger è ferma fino al 22 Marzo.

Allego due foto (non so perchè, non mi fa le anteprime, comunque basta cliccare)

IMHO

cero9 il tuo discorso fa un pò acqua da tutte le parti
primo sei un "nuovo iscritto" e stai chiedendo che ti vengano inviati dei fondi, difficilmente qualcuno entrerà nel tuo progetto
stai utilizzando bitfinex che non è uno degli exchange piu affidabili, anzi...

Questo è comprensibile.
Purtroppo non sono molto partecipe sul forum quindi non è sicuramente una cosa positiva per questa idea.
Non credo tuttavia che un alto numero di post sia indice di affidabilità.

Con Bitfinex mi trovo bene, perché dici che non è affidabile? Altrimenti quale mi consigli?
Quote
questo poi non ha ancora piu senso e ti spiego perchè
tralasciando il fatto che non è possibile inviare sugli exchange € o $ se non al proprio conto, mettiamo che ti mando 1 BTC oggi che vale mettiamo 2000$, tu segni la mia partecipazione come 2000$, domani il BTC crolla e vale 1000$, come fai a ridarmi i miei 2000$?!
Perché facciamo surface trading; se i BTC sono in discesa, a meno che non cadano di colpo, avranno anche in questo caso alto e basso e scenderà gradualmente.
Immagina quindi delle "onde", dove la seconda parte in discesa sarà più lunga della prima in salita, ma se c'è l'onda, c'è l'opportunità di guadagnare.

poi vabbè questa è la ciliegina sulla torta XD


Ok

Ciao a tutti,
Non partecipo molto alle discussioni ma è molto tempo che leggo e mi informo.

Ho iniziato da qualche mese il a fare trading di criptovalute con Bitfinex, utilizzando un software che comunica tramite le sue API.
Di fatto è un trading automatico che si basa semplicemente sulla media mobile dell'ultimo arco di tempo.

Lo scopo non è sperare in aumenti o ribassi sostanziali del valore dei BTC (o di tutte le altre valute), ma semplicemente approfittare dei piccoli alti e bassi che sono sempre presenti.

Un esempio: 7 minuti fa ho acquistato 0.1 BTC a 2205.8 USD, e li ho rivenduti, automaticamente, pochi secondi fa a 2215.4 USD.
E' vero, il guadagno è molto piccolo, ma la forza di questo sistema è che è assolutamente automatizzato e attivo 24 ore al giorno. Immaginiamo di avere decine, idealmente centinaia, di acquisti e vendite di questo tipo nell'intero arco della giornata e tra diverse criptovalute.

Sono qui per proporvi di partecipare a questo "sistema" di trading che sto utilizzando.

Vorrei trovare persone interessate ad investire insieme a me in questo sistema. Potrò aggiungere ulteriori capitali al mio account di trading e dividere, su base mensile o settimanale, i proventi del trading automatico, ovviamente in proporzione alla quantità di soldi inviatami.

Perché lo faccio? La mia idea è di tenere il 5% sui dividendi. Quindi, prendo la mia parte solo se c'è un effettivo profitto, facendo comunque tutto il lavoro.
Garantisco in cambio un server dedicato a questa attività, attivo 24 ore al giorno, ed una connessione a fibra ottica a bassa latenza per minimizzare i ritardi negli ordini.

Non posso invece garantire un ROI, come immagino sappiate non c'è alcuna sicurezza in questo tipo di attività, soprattutto con criptovalute. Tuttavia, i miei risultati finora sono decisamente interessanti (una media di 10€/giorno con un investimento iniziale di 560€). Propongo questo tipo di attività perchè ho avuto modo di testare l'effettivo funzionamento del software, ma non ho molti capitali miei da investire.

Ci tengo inoltre a precisare che il valore della valuta ha poco a che fare con i proventi di questa attività. Preferisco che eventuali contributi mi vengano inviati in euro o dollari, ma in caso di invii di BTC, potrò non essere in grado di tenere "il passo" se il valore del BTC aumenta troppo velocemente (come dicevo, guadagneremo dagli alti e bassi quotidiani della valuta, e non dal suo aumento di valore nel tempo). Il discorso ovviamente vale anche al contrario: se i BTC si svalutano, la partecipazione non sarà ridimensionata.
In questi casi, pur potendo ricevere BTC, il contributo sarà considerato in dollari al cambio del momento della ricezione.

Posso comprendere ovviamente i dubbi nell'inviare soldi ad una persona conosciuta via internet, per questo motivo posso accettare anche contributi tramite PayPal o simili.

A qualcuno interesserebbe partecipare in modo da creare effettivamente questo gruppo di "surface trading"?
6  Bitcoin / Mining support / Re: Mining speed slower on pool than on web interface on: January 20, 2016, 09:57:27 PM
Thank you all, I'm not sure but I think it's overheating and it probably started slowing down when I swapped the fans.

I still can't figure out the difficulty thing: isn't it slower to process more difficult hashes than easier ones? If it is, what does the 1TH/s speed refer to?

If it doesn't, why bother about difficulty at all?
7  Bitcoin / Mining support / Mining speed slower on pool than on web interface on: January 19, 2016, 12:42:59 AM
Hello, I'm quite new to the bitcoin world.

I'm facing this strange issue, I'm running a Dragon Miner T1 which should run at 1TH/s.
When I log into its interface I see, in fact, that it's running at the said speed, but, when I log into the pool, I can see a quite lower speed, something around 500 - 600GH/s usually.

Do you have any hint how this might be possible?
I replaced its fans so I might think it might be an overheating issue, but I don't understand why, on the miner page, it says the right, full, speed.

I also made some tries changing difficulty - don't think it matters, but I'm also not sure what to set

Any help?
Thanks

I have no idea. The temps are made available to cgminer via the controller board and this should work out of the box.
Which version of the miner do you own?
I've got a T1, do you mean that?
If you mean the cgminer software version, the one that's bundled into your firmwares, but I'm pretty sure that it also didn't work with the original one
9  Bitcoin / Hardware / Re: [Enhanced Firmware Mod] Dragon Bitcoin Miner ALL (1T,1.5T,2T) versions on: January 18, 2016, 03:07:53 PM
Haha, now i got you. I fixed (with Sugru) the additional two fans on the back to assist the front ones with blowing hot air out of the case.
I understand, I will try something like that!

Any hint about the temperature not showing?
10  Bitcoin / Hardware / Re: [Enhanced Firmware Mod] Dragon Bitcoin Miner ALL (1T,1.5T,2T) versions on: January 18, 2016, 02:03:28 PM
I also tried to undervolting hoping to save some energy and, mainly, to keep temperatures a bit lower.
Do you think it might work? It says that the minimum voltage is 600 (which is? 6V?), I put 580 but I'm not sure it's applying.

I tried with 500 but only two of the four cards were running, so I guess it works, but if so, I don't understand that text.
11  Bitcoin / Hardware / Re: [Enhanced Firmware Mod] Dragon Bitcoin Miner ALL (1T,1.5T,2T) versions on: January 18, 2016, 01:32:25 PM
No need for excuses, glad when i can help. The controller board has sockets for up to three fans.

To use more than three fans, you have to use a splitter like this:
http://www.scan.co.uk/products/akasa-pwm-fan-splitter-supports-2-pwm-fans-from-a-single-motherboard-pwm-header

As far as i can remember, the default view in "miner.php" does not display the temp correctly. You can switch to either 'Kano' or (afaik)  'Mobile' view.
Yes I found that, I was just asking "where" did you set up those fans?
I mean, I replaced the two that were already there with these new fans, but the other two? In series? Did you cut new holes?

About the temperature, still no way.
Even in the mobile view, the temperature column is just empty.


This also happened on the official firmware
12  Bitcoin / Hardware / Re: [Enhanced Firmware Mod] Dragon Bitcoin Miner ALL (1T,1.5T,2T) versions on: January 18, 2016, 09:21:15 AM
Thank you, got it!

The stock fans are horrible! I replaced the fans with 4 spare arctic fans i had spare.
http://www.memoryexpress.com/Products/MX49912
Hope that helps! Got it down to 35dB.

Ps.: A new 8GB Image is ready, but i am on the road and will upload tonight.
Sorry to bother you again this issue, but the miner only has two fans. The other two are referred to the PSU?
Did you also replace them? Or did you made some mod to the case?

How do I check temperature? I see that voice on the log table, but it's empty
13  Economy / Computer hardware / [WTS][EU] Dragon Miner T1 1TH/s 800W new PSU, new fans on: January 17, 2016, 05:57:53 PM
For sale:
Dragon Miner T1

- 1TH/s
- 800W consumption and new 1kW PSU (I'm not sure about the "real" power consumption: it sells with an 880W PSU but it says that it's 120W more than needed and gives a little space for overclock. Anyway, I replaced it with a 1000W PSU to avoid overheating and ensure stability)
- new 120m Arctic fan - really quiet! Original fans were very noisy. Before, it was comparable to a vacuum cleaner, now to a desktop computer (noise-wise)




I'm not sure about the price, so make your offer!
I accept PayPal, BTC and other if you prefer!

I'm from Italy, in Europe.

Thanks

There's one thing I don't fully understand:

On this firmware (like on the stock one), there's space for three pools.
I don't understand if the hash power is split between those pools or if the second and the third are used as fallback.

Does someone know that?
15  Bitcoin / Hardware / Re: [Enhanced Firmware Mod] Dragon Bitcoin Miner ALL (1T,1.5T,2T) versions on: January 09, 2016, 03:03:25 PM
As quiet as it can be. My gaming PC is louder  Cheesy
Sorry to bother you again with this non-so-relevant issue, I just found that I bought the non-PWM version of these fans, while the ones in your link have PWM.
Do you think that it will affect the noise? As far as you know, is there any kind of PWM support in the board, or they will just work the same? Or the support is not even needed?

Thank you, can't wait!

Can I ask you why the Pi needs overclocking?
It's not what i would call overclocking. Modest mode is really safe, but can also be disabled if you want. It's giving cgminer more CPU power. More relevant ist the memory that i adjusted for server runtime. It is
split.gpu_mem=16

Ok, I don't think I fully understand what you mean, I'll do some researches when I get home!
And will, of course, install the firmware!

Thanks, I just bought four. How noisy is yours? Compared to a desktop computer?

I'll be back home in two days, can't wait to try the new firmware!
19  Bitcoin / Hardware / Re: [Enhanced Firmware Mod] Dragon Bitcoin Miner ALL (1T,1.5T,2T) versions on: January 08, 2016, 09:17:22 AM
Hello,
I received mine some days ago, the problem is that it's really noisy!
My idea was to keep it in my apartment, because I thought it would make the same noise as an old desktop computer, but it's way louder!
Do you have any hint about making it less noisy? Some replacement fants or something else?
Thanks

Links are not working, is it uploading?

I have a question: my T1 doesn't have a LCD display. Is that possible? I'm not sure that it's a Dragon Miner T1, that's what the seller said, but I'm sure it doesn't feature an LCD display (but it has a "hole" on the case, maybe it can be plugged in?)
