How to backup a btc-qt wallet?

Step 1. Click on the File menu
Step 2. Click on Backup Wallet...


It is not necessary to back up your wallet every day. You must back it up at least every 100 sends.

OK, thanks a lot for the analysis guys, really appreciated.

So, to optimize ROI, we should calculate at which point it makes sense to switch to another security that pays more dividend. Unless DMS comes up with something that increases dividend. This is also why I mentioned P/E earlier.

In theory, switching won't help because as as the dividend drops, so will the price of the share. The dividend can rise if the difficulty drops.
8643  Economy / Securities / Re: [BTC-TC] Deprived Mining Speculation (DMS) on: June 17, 2013, 06:36:51 AM
What I don't get is that DMS MINING pays a dividend of roughly .5 percent, per day. As listed above, this should be about 180 percent return per year. Shouldn't this thing be going through the roof?

We need to develop reliable P/E ratios for all of these securities to have another common denominator.

180% per year is not correct because you don't get your original investment back, so really it is only 80%. But then, as TradeFortress stated, the dividend drops as the difficulty goes up. There is a possibility that you wont reach 100%, which would mean that you lose money on your investment.

Here is what will happen to the 2-week dividend over a year if the difficulty increases by 20% each period (a rather pessimistic prediction):



In this case the total revenue is about 40%, so you lose 60%.

If you assume a certain average rise in difficulty, you can compute the total amount of revenue you will receive. Here are some examples:

Difficulty Change| Factor| Total Revenue| Total Return
20%| 6| 40.5%| -59.5%
10%| 11| 74.2%| -25.8%
5%| 21| 142%| +42%
2% (Moore's Law)| 51| 344%| +244%
1%| 101| 681%| +581%

Does the exchange have a history of transactions for your account? Maybe the transaction history will shed some light.

8646  Bitcoin / Mining speculation / Re: Google Spreadsheet with some 2013/2014 difficulty estimates on: June 17, 2013, 03:39:04 AM
Just for fun while waiting for Avalon to get around to shipping B3 units, I created a google spreadsheet to project the estimated BTC generated for a given hashrate received at a particular time during the year.  Is it pretty easy to use... just put in your expected delivery date in the yellow box, and your hash rate in the green one.  Feel free to try it out!

https://docs.google.com/spreadsheet/ccc?key=0Auya3iRE6az1dG9fRkpXdFJtT1dNX0VCU1F0VFFUX3c&usp=sharing

To get the projected hashrate I used historical some data points starting in mid January through this last for difficulty adjustment (6/16/2013) and used and exponential fit in wolfram alpha.
...
One caveat:
Wolfram alpha's best exponential curve seemed a bit optimistic on growth rate. I upped it a bit to what I think would be more conservative (but who knows?!).
These projections put the difficulty at 100M+ at the end of september, and 1B+ at the beginning of March 2014.

I am not sure how to allow you guys to make your own edits without saving... so if you want to edit, you will have to make a copy I'm afraid.

It is impossible to get an accurate prediction with just extrapolation. There are 4 more pieces of information you could add to make the predictions much more accurate:

1. How much hashing power is expected to ship over the next year or so (and when).
2. The difficulty rate of change at which an ASIC costs more than the amount it will ever mine.
3. The difficulty at which electricity costs make it unprofitable to mine with an ASIC.
4. The difficulty at which electricity costs make it unprofitable to mine with an GPU.

You are a newbie. I'm not surprised that you have never heard of it, but your ignorance doesn't make it a scam.

8649  Economy / Securities / Re: [BTC-TC] Deprived Mining Speculation (DMS) on: June 16, 2013, 03:31:22 PM
The dividend return on SELLING is more than 4x higher than the dividend return on MINING (compared to their current price per unit).

Keep in mind that DMS.SELLING dividends work just like stocks. Dividends are not like interest -- you don't gain anything by receiving dividends. A dividend just converts share value into cash. Assuming the value of DMS.MINING is unchanged (it is unaffected by the DMS.SELLING dividend, after all), then the NAV of a DMS.SELLING share will drop by the amount of the dividend because the dividend is paid from the capital that determines the share's NAV.

For example, suppose the NAV of a share is 100 BTC (because it is backed by 100 BTC of something). Paying a dividend of 1 BTC will lower the NAV to 99 BTC because it is now backed by 99 BTC of something. After the dividend, you still have 100 BTC -- 1 BTC plus a share worth 99 BTC.

Also, keep in mind that mining dividends are different.

There are other factors in play here, so although this is a fundamental concept, the results could be different.

I was worried that a paper wallet might be destroyed by water if it caused the ink to bleed, making the qr code and text unreadable, so I experimented.

First, I printed some paper wallets on my cheap printer. Then, I applied varying amounts of Krylon acrylic spray in different ways and dropped water on the paper.

1. 1 coat on the front and wet the front.
2. 2 coats on the front and wet the front.
3. 3 coats on the front and wet the front.
4. enough acrylic to soak the paper and wet the front.
5. 1 coat on the front and wet the back.
6. 1 coat on both sides and wet both sides
7. wet the front of unprotected paper

I allowed the paper to sit until it was dry.


Here are the results:

Unfortunately for the experiment, the ink that my printer uses (Epson DuraBrite Ultra) resists water very well. The #7 unprotected ink was mostly unaffected by water. It smeared noticeably in one area, but not enough to affect the readability.

Assuming that not all ink is so resistant, here are my other observations:

#1, #2, #3, #6 - A single coat is sufficient to prevent the water from soaking into the paper, but multiple coats make the surface of the paper shiny.

#4 - Soaking the paper with acrylic tended to reduce the contrast of the paper and cause the ink to bleed very slightly, but not enough to make it unreadable. Other inks may behave differently.

#5 - Because the ink was water resistant, it was not possible to tell if coating one side protects the ink from water on the other. I suspect that it might.


Conclusion:

Coating both sides with acrylic spray protects the ink from water very well. A single light coating is sufficient. It might be sufficient to just coat the side with the ink. Some inks resist water, and coating paper with acrylic spray may be unnecessary. Spraying the paper with enough acrylic to soak it is not a good idea.

But anyway something tell me that 60% the of Deprived Mining Investors doesn't understand the SELLING Fund  especially the maths.
What leads you to believe that 60% don't understand?

I think I am part of the 40% that understand what is going on. At least, I hope so. Are you sure you are not part of the 60%?

8657  Economy / Securities / Re: [BitFunder] [TAT.VIRTUALMINE] Virtual Mining - Hash Without Hardware! on: June 15, 2013, 02:59:57 AM
If the price of VM drops to .0001 then buying them at the price you'll have 188x the dividends of AM in a week. It wont drop to that low.

I meant drops by 0.0001, not drops to 0.0001. If VM drops, from 0.0070 to 0.0069, for example, then your 420 shares have lost a total of 0.0420 BTC, which exceeds the difference between the 0.035 BTC from AM and 0.0758 BTC from VM.
8658  Economy / Securities / Re: [BitFunder] [TAT.VIRTUALMINE] Virtual Mining - Hash Without Hardware! on: June 15, 2013, 02:49:08 AM
Even with difficulty calculated it will still outperform AM shares.

boyohi,

It is important to include the price of the shares in your computation. If the price of a share of VM drops by 0.0001 over a week while AM remains constant, then both will have the same return.
8659  Economy / Securities / Re: [BitFunder] [TAT.VIRTUALMINE] Virtual Mining - Hash Without Hardware! on: June 14, 2013, 04:55:53 PM
why are people trying to ditch shares sub ipo righ now ? i dont know why people would do that unless its the dot com crash in the 90s

This is normal. In general, if the difficulty goes up, the dividends will be lower and the shares will be worth less. The price is falling because the difficulty is rising.

INVESTMENTS

One of the stated objectives of this fund is to generate some revenue from our capital rather than just have it all sitting around idle on BTC-TC.  There are two stated methods by which this will be achieved - investment/loans to existing businesses and secured personal loans.  In this post I'll be addressing the former of those (a proposal will be put forward about the latter in a few days time).

BALANCING THE NEEDS OF TWO GROUPS OF INVESTORS

There are two primary groups of investors with an interest in capital managed by DMS : holders of MINING shares and holders of SELLING shares (PURCHASE holders are effectively members of both of those groups).  The interests of these two groups of investors are not aligned with one another when it comes to management of our capital.  

  • It would be in MINING's best interest if capital were just held wherever is the safest - be that on BTC-TC or in a private wallet of mine - as in most scenarios they gain nothing from any profit it generates ut end of losing out if there's any large loss (in general a loss of under 10% will never affect them, a loss of over 70% definitely will by triggering a forced closure).
  • It would be in SELLING's interest to invest wherever the likely EV (Expected Value) was highest.

A couple points:

MINING also has an interest in growing the capital. There is a risk (albeit very small in my opinion) that the current capital is not sufficient. That could be the case if the difficulty drops in the future.

I think it is very important to avoid underestimating the impact of counterparty risk. Most losses to bitcoin investors have been due to counterparty risk. History shows that even the most secure and stable investments available in bitcoinland are extremely risky. Personally, I don't think that SELLING shareholders would object to holding most of the capital in bitcoins. It might even have the highest expected value.
