$100B transferred by PayPal in one year? What's special about a year? You can't compare total value of bitcoins to an amount of money flow in PayPal over an arbitrarily chosen time period.

Maybe he wants to withdraw some of the profit to his wallet outside Bitcoinica.

As I understand it, when a Bitcoinica customer goes long more than that customer has USD balance for, or goes short more than he has BTC balance for, he is effectively borrowing from the balances of other Bitcoinica customers to do so. That's what Bitcoinica is all about: pooling resources of varied customers to facilitate trading beyond their means. Of course this requires that either some customer balances aren't being fully used, or some of their positions are in the opposite direction of others'.

This means when Bitcoinica customers are predominately long, you may not be able to withdraw USD or go long or cover shorts because others have borrowed your USD. Vice versa for withdrawing BTC, going short, covering longs, when most are short.

Am I on track zhoutong?

Do you have many completed or almost completed Rev A units that you'd consider selling with a drastically reduced clock to keep the heat and power draw within spec, with a deep discount to correspond with the low hashrate? I wonder if you might have boards that are now otherwise useless because of the discovery of higher power draw than expected.

With $599, $3.10/BTC, $0.115/KWh, 830 MH/s, 80 W, and current difficulty (1155038), it will take 9.75 months to pay off an investment in BitForce Singles. I want a warranty that assures me the hardware will last at least that long.

BFL: Please consider offering a 1 year warranty, perhaps for a small additional fee if you must.

Oops, I meant W/GH, not W/MH.

Keep in mind that 40W more power only costs you about $40 per year more in electricity at typical US rates. (using 11.4c/KWh to make the numbers come out easy)

I like to use 1 year for projecting whether such a mining device is worth investing in. So go ahead and give me a device that uses 60W instead of 20W, discount the purchase price by $40, and I'm happy. A year from now, surely I'll either be out of bitcoin mining altogether, or will have upgraded to much better hardware anyway.

At this point, I mostly just care about $/MH. I can build GPU rigs at about $0.60/MH, and they have more certain future resale value. I'm willing to pay up to $0.75/MH for FPGA-based miners, because going from 400W/GH to 60W/GH is a major savings in power cost, and it's much easier to deal with the heat. At $2.50/BTC at current mining difficulty at 11.4c/KWh, a $0.75/MH 60W/GH rig recoups its cost in 11.5 months.

In my opinion, ROI is becoming the primary factor in bitcoin mining, not so much W/GH. I think few serious investors want to pour money into mining rigs without a good chance of getting it back in a year.

Got it. My funds have been restored to my account on the new server and I put my orders back up. Thanks

I sent an email to sales@bitcoin2cash.com 21 hours ago, requesting that my account be restored on the new server. No reply yet...

I'm not quitting yet. But below $5.55/BTC, I'll have to idle my miners, and buy on the market instead if I want to continue increasing my holdings.

Although I haven't verified the details, I want to say that yes I was in the channel while this was going on, and have no reason to doubt the above account.

I am unable to withdraw BTC from bitcoin2cash.com.

But the order matching problem was probably just a rounding bug. I had no problem selling 4 BTC at $12.99 (to ensure overlap with the bid at $13.00).

Funny I run across this thread right now...
I'm in the USA and do business with someone in China regularly. But it's annoying paying fees to banks for moving money back and forth. He recently got into bitcoin mining and will be selling at least some of it, so paying me with bitcoins instead of trying to sell bitcoins locally will be win-win! It's the same situation in the other direction as well.

When you're back on IRC, pm me there and be patient. I'm willing to trade my BTC for your SLL.

You guys are lucky. I've been trying for 3 hours to just get the first page to load! My first attempt to load the page a few hours ago did work, but after trying to submit the first form, it went AWOL and never acknowledged the submission, and I got no email. Since then, the page has never loaded despite many attempts and much patience.

It amuses me that some people have been wanting to invest in bitcoins for weeks, but haven't been willing to pay even 1% to get money into the most liquid exchange. Meanwhile the price has soared. What's 1% compared to 1460% gain in just about 5 weeks?

Are you selling BTC and accepting PayPal?

Unfortunately some shortcomings currently deter me from setting up a nice realtime graphical interface for that. For example, the feed doesn't provide the current order book upon connection start, and pulling that from another page would be quite tough to sync properly. I've also heard the feed omits some data sometimes, though I haven't verified that.

I was going to make a nice interface for the feed as well, but I'm not going to bother until the problems are resolved:
Rounding issues
No perfect way to start out in-sync
Alleged missing data and dark pool inconsistencies

Are you able to pay with a better method than PayPal? Do you have a bank account in the USA? Is it Wells Fargo, Chase, ING Direct, or any on the Popmoney list?:
