Can someone explain me what's an easy calculation I can make to see when the next dividend of B.SELL will be paid?


Many thanks

Hello,


I'm searching for a good Scrypt miner, possibly which can be bought in Europe.

I've found this one: https://www.usbminers.nl/Gridseed-mining-starterskit-easy-plug-and-plug-scrypt-mining

Is this website secure or a scam?

I see the same miner here, with a different price:
https://minereu.com/product/gridseed-miner/

Is this because it can also mine BTCs? I'm not interested in BTC/Scrypt, I'd like the Scrypt only one. Has gridseed ever done a scrypt only miner and, if not, how do you justify such a lower price from usbminers.nl?

Thanks!

Very good, no complaints. Thanks!

Qualcuno può darmi qualche dritta riguardo alla fatturazione di vendita/acquisto bitcoin in volumi elevati?
Esistono exchanges che rilasciano fattura al momento dell'acquisto? Oppure potrei farla io?

Supponiamo che guadagni una cifra molto elevata su un cloud miner (tipo cex.io): è chiaro che non posso inquadrarla come stipendio. Bisognerebbe fare una partita IVA, ma come fatturare le spese (cioè l'acquisto di bitcoin)? È possibile?

Grazie in anticipo

Because I've concluded the price of a KH/s is destined to exponentially decrease over time. A price of a GPU card is too, but the drop is not exponential.

I've concluded this based exclusively on Bitcoin cloud mining (see https://cex.io/), the situation might be different with litecoins and other scrypt currencies. I will check out the link you sent me, it looks very interesting. Thanks!



I still don't know what PSU to buy, since I don't know which GPU models I'll use and how to correctly compute the required voltage. Thanks for pointing out this problem!


Seems better indeed, thanks! I hope my reseller have this. I cannot import expensive goods from the US without paying, so I need to buy gears inside of the EU. PCI risers cost 9$ on amazon but if you live in the EU prices starts from 12€ ( = 16$) which is insane. Not to mention the powered ones, which I saw for prices starting at 25€.

This one? Yeah, I was wondering also how to manage the power supply. Do you think 2 GPU draining from the motherboard and 3 from an external PSU can be good? Thanks!

Thanks for your reply and help!
So, those connectors labeled PCIEX1_1, PCIEX1_2 and PCIEX1_3 are meant to be connected to a GPU, right?

If I had 5 of these:

In order to work properly I'd just need 2 of these:

and 3 of these:

Together with a power supply unit, cpu, ram, hdd. Do you think this can work? Or, perhaps, some software problems may arise in using 5 gpu's?

Sorry for sounding like an idiot, but I've never done this before and the most manuals on mining are all like: "oh yeah, just connect some cables, download some shit and press some buttons dude..."

I've read somewhere that this motherboard can hold up to 5 GPUs: http://[Suspicious link removed]/NXTZC4

However, as I asked my reseller if this was true, he replied that it can hold 2 graphic cards on PCI-Express 16x slots in crossfire mode.

Can someone explain me what does it means? This is the same article on the reseller page: http://[Suspicious link removed]/NBjadK, it really looks like the same product to me.

Do I really need crossfire mode? Can I connect 5 GPU do that motherboard, install windows and start mining at full power?

EDIT: since I can't post links, here's the name of the motherboard.

Thanks for your help!

Is there any website or application where I can insert the id of a bitcoin address and visually see all the transactions and movements associated?

I'd like to see that as a node graph, something like this:

I was about to develop something myself but that would be very time consuming. I was wondering if anyone made this already.

Also, how would you do that? You may represent btc movements in any given time using a graph, but I'd like something which can show the "flow". For example, if A has 10btc and sends 5btc to B, I'd like that, if you visualize the wallet A, you'll also see the wallet of B but also be able to understand from where those 5btc are coming from.

Hello,

I'm getting crazy with this! I've downloaded the whole block chain and the index from the official sourceforge page. Then I putted them in Username/Library/Application Support/Bitcoin and deleted all the logs and db files as required. Now Bitcoin-QT crashes as soon as it tries to load the block index!

I tried to delete the index, it then works but the application starts the process of syncing with the network again from the beginning (and it goes damn SLOW! Even if it has the block chain already).

Any clue on what's going on? Thanks!


p.s. With other attempts I also got the fatal error "11dbexception db::open:" but it looks like I'm not able to recreate this anymore.
