1  Other / Beginners & Help / Newbie orphaned block transaction fees question. on: May 31, 2013, 06:23:55 PM
 My question to try and better understand what us on the wiki, is what happens to the transaction fees associates with transactions that were processed in the orphan blocks? I know the teansactions themselves are queud to be added to the correct blockchain but surely there's no way to take the bitcoins off the miner that generated the orphan block? If the transaction fees simply disappear doesn't that mean we will eventually over time lose bits of bitcoins until we start running out!?
2  Other / Beginners & Help / Teamviewer and guiminer conflict? on: March 29, 2013, 04:51:48 PM
Title says it all.

I've used guiminer now for a few days and was getting a consistent hashrate of about 200mhs on one of my gpus.

I'm away from my pc for a while so rather than using remote desktop (which I've used just fine for remote management) I decided to try teamviewer.

Having installed teamviewer my hashrate dropped, and eventually guiminer gave up and stopped hashing.

Is this normal? Uninstalling teamviewer seems to have fixed it!

3  Bitcoin / Hardware / Fpga bitcoin mining available? on: March 28, 2013, 04:43:52 PM
Bit of a newbie question but here goes:

Given that I cannot buy Asic hardware, and I want to move from GPU to the next level (although the price rise in bitcoin has more than compensated for the difficulty rise my gpus face). Is there anywhere I can buy FPGA miners from, that will actually be delivered in a timely fashion (i.e. in stock)?

I did not get an avalon (did not have the btc to hand) and they probably wont offer a batch 4.
I no longer believe BFl will ever deliver Asics.
I want to own the device (so asicminer shares are a no go)
I dont want to buy bitcoins with fiat.
I have fiat and want to generate bitcoins, as I currently do with my gpus, but with Fpgas (preferably 800mhs+)
I want to buy the Fpgas with fiat.
I am semi tedhnical with gpus, but have no experience with fpgas. So they would need to have bitcoin mining hardware available and be reasonably well supported (ie usb drivers for windows pcs).

Any currently in stock fpgas available? Or opinions on this?

Thanks!

4  Other / Beginners & Help / Best uk gbp exchange to sell my bitcoins on? on: March 09, 2013, 08:00:54 PM
Apologies for (yet another) newbie question.

I have a small regular bitcoin income that I would like to exchange for uk GBP .

I have looked at bitpay.com (awaiting verification, but not hopefull as it seems geared to companies rather than indivuduals) and mt.gox, but am worried about the two week wait.

Are there any reputable uk based exchanges that handle speedy currency conversions and withdrawals to a uk bank account?

Thanks!

5  Other / Beginners & Help / Avalon Asic Power requirements on: March 04, 2013, 08:07:49 PM
Hello,

Not a genuine newbie anymore, but this is a "noob" ish question.

Does anyone know if the PSU in the Avalon Asics can cope with 240v 50hz mains power (UK) or will it require a transformer/adaptor?

If so will a standard American to Uk transformer (120v 60hz->240v 50hz?)

Thanks!

6  Other / Beginners & Help / Asic difficulty newbie question. on: February 02, 2013, 04:28:18 PM
Hi all,

This may be a silly newbie question, but I'm going to ask anyway!

Everyone seems to be implying that Asic chips will increase the difficulty (I've read between 5x current and 20x)

But it seems to me that if difficulty goes up, those with inefficient mining systems (cpu/gpu and possibly some fpga's)  will be minning at a loss when factoring in power consumption. If this is true wouldnt they simply quit mining? Thereby lowering the difficulty. . . .

I often read on this forum that the current difficulty makes mining only barely profitable (or are people just trying to stop newbies from going into mining?) if so, it would only take a very slight increase in difficulty (say 2x) to make exisiting mining completely unprofitable . .  And so overall difficulty will not increase by as much as everyone seems to expect?

I realise this is based on a lot of assumptions. But I would apreciate a reasoned logical response as I am only curious!

Thanks!

7  Other / Beginners & Help / Wallet encryption backup on: January 20, 2013, 10:14:49 AM
Hi,

Newbie question here:

I have chosen the option in bitcoin-qt to encrypt my wallet.dat file.

I have used a reasonably good password (20+ charachters, upper lower numeric punctuation etc.)

Is this wallet safe to backup in say dropbox without extra precautions?

The question really is does bitcoin-qt do a good enough job of encrypting my wallet.dat files private keys?

Thanks!

MyrddinDC

Is http://wallet.it.cx down?

Is this down permanently now?  Huh I was using it to try out litecoins. I appear to have lost them now!
