With the current LTC difficulty (0.61881515), LTC price (0.015984) and 1 khash/sec, you can make $0.78 per month.

The average seems to be about 0.30 khash/sec or so, though, which would be $0.23 per month.


Unless you can get at least 1 khash/sec, this doesn't seem to be worth registering for.

What?  Really?  Do you have a source for this?

Where I live, we call that "summer". 

Winter temperatures rarely go over -10C.

It depends on the speed of the server and how many orders there are.


A while ago (many weeks), I saw someone try to buy a large number of bitcoins.  There were tons of tiny sell orders (for 0.01 to 0.10 BTC).  It took so long that one single purchase took 7 minutes to complete.


While I haven't seen large amounts of lag like that recently, I would expect that it would take a while for mtgox to process a $1,000,000 order, since it would clear out the entire order book.

0.60% is the highest tier.


A bot would have 0.30% to 0.25%, depending on its volume.

IMO, this would be the best possible thing that could happen for bitcoin.


It would be like FDIC for bitcoin.

MtGoxLive changed the way it displays the buy/sell lines recently.

Before, it would draw horizontal lines between orders.   Now it draws ramps instead.

Bitcoin is not a stock.

Companies can go bankrupt if they loose too much money.  Bitcoin is not as easy to kill.


If bitcoin was a company, it would be a company that doesn't have to pay for employees, a building, advertisement, etc.

The current 30 day volumes for those sites at the time of this post... 
(See http://bitcoincharts.com/markets/ for current numbers).


6,136,000 USD for MTGOX
619,000 USD for TH
293,000 USD for BTCE

Now let's calculate their monthly income at 0.6% commission that is taken from both sides of the trade...

MTGOX... 6,136,000 USD * 0.006 * 2 = 73,632 USD
TH... 619,000 USD * 0.006 * 2 = 7,428 USD
BTCE... 293,000 USD * 0.006 * 2 = 3,516 USD


You are off by nearly an order of magnitude.

The lowest commission rate at mtgox is 0.25%, so let's use that as a minimum...

MTGOX... 6,136,000 USD * 0.0025 * 2 = 30,680 USD
TH... 619,000 USD * 0.0025 * 2 = 3,095 USD
BTCE... 293,000 USD * 0.0025 * 2 = 1,465 USD

My shutdown point is $0, since I use my computer to heat my house. 

For a hardware enthusiast with $.05/KWH energy, it's never too late.




If you buy bitcoins, you can only make money if the price of bitcoins goes up.


If you buy hardware, you can make money even if bitcoins stay the same price.

If you don't mine, someone else will.  I wouldn't worry about the impact of mining.

Some programs I need don't run under Windows 7.


I'm not sure what you mean by this.  I can run two GPUs just fine.

-Windows XP 32 bit SP3
-Two Radeon HD 6870's... one from HIS (H687FN1GD), one from Sapphire (100314-3L)
-Motherboard: ASRock P67 EXTREME4 (B3)
-Driver: Catalyst 11.6



My problem was that guiminer (using OpenCL) doesn't show the second card unless it has a monitor active.  

In Windows, it seems that not only do you need a monitor plugged in (or a dummy plug), but you also need to set the monitor as active (Desktop -> Properties -> Settings -> "Extend my Windows desktop onto this monitor").


This is really annoying for a computer that actually gets used (as opposed to a dedicated bitcoin mining computer) for several reasons:
-my cursor will go off of my screen when I move my cursor past some of the edges or corners (depending on the "location" of my fake monitor)
-causes some bugs/problems with programs that don't support multiple monitors
-causes some bugs/problems with programs that DO support multiple monitors (since they will assume you have both monitors on)
-screenshots will show both screens (the real one and the fake one)
-windows will often open on the wrong monitor (either partially or completely)


I don't mind the need for an extra monitor or dummy plug, but the need for it to be an "active monitor" is a problem for me.


Is it possible to get around the need for two active monitors?
