It's different here for gambling though, we barter over odds and positions but any wins are tax free.

I highly doubt that you could get away with calling it gambling, any more than buying a beanie baby and hoping it goes up in value is gambling. The biggest reason is you are not gambling *against* anyone in this case. But law is a funny subject and you can make arguments that a horse is really a cat if you can find the right case studies.

Barter doesn't mean haggle. Barter means I trade Good A for Good B. In the US, if my wife barters her massage therapy skills for a car wash, she has to pay income tax on the fair market value of the massage, even though she never got any cash.

I read Mt Gox takes 1%, is this true? At a 34414 volume, thats 344 BC profit today, ~ nearly $3,000. For such a simple site that's impressive. There's such a huge gap in the market for a competitor here.

It's a little less than that. Like .6x% Maybe .65 if I remember correctly. Still a large number, especially when there are days with 70,000+ moved around

Gold has use other than selling it to someone for profit. If Gold's value was constant, it would still be useful as a currency. Currency is good to have because it is almost universally accepted, so it removes the need to barter, and because it's easy to price things and compare alternatives.

If I want alpaca socks, and I can offer computer programming skills, I'll need to find an alpaca farmer who also wants my skills. Pretty rare to find. But perhaps he wants a chicken, and a chicken farmer needs my skills, so I go trade with the chicken guy first, then trade with the alpaca guy. This is expensive even in the simplest case. When I trade through intermediate goods, I need to be sure that they will be accepted when I trade for what I really want. If I use a currency, I can trade my skills to anyone who has currency, then trade my currency for whatever I want. It's much more divisible than many items (I could trade a goat, but I can't easily trade 1/10th of a goat). A goat may die or get sick, whereas currency will always be currency.

Sure, speculation is a part of the market. Bitcoin is not really playing out as a currency *at the present time*. It's still more similar to trading goats, since not everyone will want a goat, and you need to go in and out of transactions. But the economy is growing, so you don't need to do those transactions anymore. As the economy becomes more self-sufficient, you'll see an increase in the usefulness of it and much more stability in the price. You should still see it become more valuable as more people want to get in (as more people contribute to the economy, with the same number of coins, the value must rise to accommodate the growth of the economy).

We are still in the super early stages. It may never reach a bigger economy. There are certain niches that it is incredibly useful for even with transferring difficulties (international transfers that typically have very high fees, and black/grey markets). Right now even those markets are in their infant stages.

The bet really is which leap (if any) Bitcoin makes. If it just becomes a significant currency for black/grey markets and international transfers, it has a huge amount to go up. If it fails completely, it will be worthless. If it becomes the standard for online payments, it goes up even more. There are a lot of longshot scenarios. But it's not just about hoping there are more suckers behind you. Although even in the fail scenario, dumping it off on a sucker could be profitable.
Great many thanks for that.

Would buying bitcoins effectively be an investment in the company/concept itself?

If bitcoins does well, the valuation of bitcoins increases, and vice versa.

I don't really see how this would ever really take off, the whole mining concept seems far to obscure for most people to understand and/or trust.

The volatility in the price will also mean people view it more as a gamble on bitcoins price rising, rather than genuinely using it for transactions.

Though the idea that for international transactions it will be greatly cheaper makes sense, the fees banks charge can be pretty ridiculous when the charge+awful exchange rate are combined, so there is definitely scope to grow there, I just can't see it becoming used for regular transactions like Paypal.

Either way it's very interesting

Thanks again,

john

.65%, but on both sides. So it's really 1.30% of any transaction gets eaten up. For 1M volume, it's $80k, so definitely good money, but there are a lot of expenses too.

I've wondered this myself how they round it off. I think they just sell you a fraction of a bitcoin, which isn't that big a deal.

If Bitcoin does well, then the value of the coins *should* go up.

Most people don't need to understand mining. Mining's a good way to get a bunch of people involved, though.

Volatility should level off at some point.

PayPal is a bigger thing to try to match. It's pointless to convert to USD and BTC just to pay someone, unless there are no other choices. However, if the conversion process becomes easy, then maybe it takes off better. PayPal is such a pain, there's a big opportunity. But then, why not use something like Dwolla? If it happens, it would be more of a merchant revolt. Merchants hate dealing with PayPal, disputes that are always won by scammers, fees, etc... It might work.

the bitcoin episode of this week in startups with Calacanis has 4x as many youtube views as any of the other 140 episodes of the show, possibly worth noting
i thought it was a cool episode regardless, cleared up some things i was confused about.

Does anyone else think it is weird that the second most traded currency with bitcoin is the Polish zloty?

Does that indicate any kind of specific use?

Might just mean that it's an easy market for Poles to get to. Maybe that exchange is just really good for Poles and no one has created one for Brits or anyone else (or mtgox is fairly easy to move money in and out of).

Poland has also had multiple episodes of hyperinflation and re-denomination time and time again rendering their paper currency worthless, so I would assume they have a culture acutely aware of the dangers of fiat currencies and the benefits of a fixed supply of money.
Or it's just random...

You are looking at super small markets. MtGox rules all. They have like a 95% market share.

It seems really tempting to create a brokerage service that goes through MtGox to make sure you can fulfill orders, but you can match up customers with each other and avoid the fee. You could charge a .65% fee to cover mtgox's fee, and .25% fee if you just trade locally. I wonder if that could make money. You'd have to set it up outside of the US and conform with whatever laws, but maybe it could work.

It might just be trivial for EUR users to just get to MtGox, so that's why their exchanges aren't used. But mostly, there just aren't that many other exchanges out there.

also just finally got my GPU (5770, IIRC) working on mining in slush's pool.

i've also got a GTX 260 sitting on a shelf that has artifacts, but I suppose that is an ideal candidate for BTC mining on a second comp

Your electricity costs on the 260 will likely make it not worth while. You may have a chance in the short term if you can stick it in your existing rig. You may not be able to have nvidia and ATI both running under Windows though (at least you used to not be able to mix the two to extend your desktop), not sure about Linux.

I made a spreadsheet to figure out the formula for what power efficiency you needed compared to difficulty.


Let me see if I can find the formula I came up with. I know I posted it on the forums. But even for the worst video cards on that list, it was still profitable to mine even when the difficulty jumped a ton.

Electricity is so small. I wouldn't go out buying crappy cards just to mine, but you'll at least make some money off of them.

yeah definitely not mixing those two cards

Is the difficult factor in this calculator accurate? Is it total number of megahashes?

Seems like picking up a 5870 on ebay for $300 more than pays for itself in a month, excepting electricity costs? That doesn't seem right =/

That difficulty is the current one. Keep in mind that it will change in two weeks, most likely going up.

You can try this calculator: http://bitcoinx.com/profit/

Honestly I think the 260 is going to be pretty borderline. The problem is that it draws a lot of power without being suited to Bitcoin. If you stick it in another machine then you have to power the mobo/cpu/memory too and it all adds up.

yeah not using hte 260 for sure. waste of time. I'd sooner get a 5870 on ebay for a dedicated mining machine

The second calculator is awful. It has no adjustment for difficulty gong up.

When I did the math, even some really efficient CPUs were profitable at the difficulty rates last week. Probably not now.

The difficulty factor tells you how many hashes you need to get a match on average (multiply by 2^32 to get the expected hashes).

So the difficulty being 250,000 means you need 1,073,741,824,000,000 hashes to solve a block. But a block is worth $350 right now roughly. So each hash is worth $3*10^-13. 1Mhash is worth $3*10^-7. You get $.0013621/hour/MHash/s on average now. The 260 gets you 36Mhash/s, so you'd just under 5 cents per hour. If your electricity costs for it are under 5 cents per hour, you are profitable.
