Re: Why I did I loose BTC in this trade sequence?
by
nfurno
on 10/11/2013, 04:17:34 UTC
I custom developed a trade bot that made alot of money during this move, let me explain to you how I look at profit forcasting on trades.

1. when you sell, you are charged a 0.6% fee, and the price is at the high point of your trade cycle.
2. when  you buy your btc back, you are also charged at 0.6% fee, and the price is at the low point of your trade cycle, so your fee from your sale was higher than the fee from your purchase.
3. this means you must cover at least 1.2% in profit JUST to cover fees, if the move in price is less than 1.2%, you lost money. If the move in price is less than 2.4%, you made gox more money than you made for yourself.

I wrote a trade backtester that has all mtgox trades ever made up to this second. It then spends days analyzing every buy/sell price combination testing which two prices would have made the most money in any given timeframe i want to look at. This data shows that longer term, larger moves are win. Moves around 12-18% are winners, they happen often enough and at a high enough margin to make you real profits.

In fact, with my trade strategy i have some fixed incremental trades programmed in, but the bot picks the rest of it's trades based on this backtesting technology i put together. It does a way better job at picking prices than i do.

Hope this helps.

on 26/10/2013, 15:25:22 UTC
I live south of boston (Near Douglas, Massachusetts) and I'll have a brand new Jupiter delivered here tomorrow.

I'd like to sell for cash, in-person.

If you like it unopened, i'd need to know by this monday morning otherwise i may decide to open the packaging after receiving it.

I also have a Corsair HX1050 power supply specifically for this Jupiter that I can sell with it.

I'd like to get $8,000 for it with the PS, but am willing to negotiate.

 i think you are fine then, it looks like you run a normal bitcoin client and keep your wallet local. it's trying to connect to other bitcoin nodes so it can get transaction and block updates, malware bytes will block unsolicited outgoing calls to IP spaces in china and other places because they are notorious for malware.

if you are not mining with this PC, it's possible that someone else is.

do a dir /s bitcoind.exe to find where that process is.

If you have enough friends to put together a few terahashes, sure, go for it.  Otherwise, you will rarely hit blocks and would be better off with a slow, steady (but small) stream of btc via shares of a larger pool.

Re: I like BFL, DO YOU ???

I love them!
i got my jalapenos upgraded to 7.5 GH each, received them a few months ago and have made triple my BTC back already!
the electricity use is so low that i expect to continue running them for a long time, especially if the price of BTC keeps going up the way it has recently.

I've also got an early preorder of the knc jupiter.  Just like i had a very early BTC order, i expect that being early to the game will help alot.

I do feel bad for folks that bought later and still havent gotten their gear, but they need to understand that they had a years of pre-orders ahead of them, and pre-ordering gear while making calculations about what the return should be is extremely risky. If i lose money on my next pre-order, its MY fault, not theirs.  I am both a beekeeper and I also keep chickens, and we never count our chickens before they hatch, nor sell our honey before it's bottled. This works the same way.

I mined back in the CPU days, solo mined a few blocks of 200btc each.  Once GPU mining started, i dropped off the radar for a few years and then got a very early buy with BFL.  after waiting nearly a year i got my 2 jalapenos (the 7.5GH upgrades ones) and made all of the money back on those in like 2 weeks.  Since then it's been all profit and even now I would not shut them down. The electricity use is tiny, i have them run by a low power laptop, and it gives me more btc to spend.

Good luck with the iphone/ipad part. Apple isn't approving apps that perform transactions in btc. You have to be jailbroken to install apps that do that.

I think they changed it so that withdraw is no longer under the trading tab on the left hand side. Clcik on the funding tab below it and you should see a withdraw tab across the top of that screen.

i forgot to share one important situation that came up recently related to my last post.
When MtGox suspended fees, that threw an exception in my code. it refused to react to the completed order because it couldn't verify what the fees were.
I found the API returned a success with a null array (Basically, "Result:Success { }")
I had to rewrite that section to watch for the success and allow 0 fee objects to be an acceptable path.
Stuff like this can really mess up your day.

I think the toughest part is the transaction logic against your database. I primarily use MS SQL and for something like this most of the time goes into the transaction code so that either all steps of the transaction succeed, or the whole thing fails and no change is made.  I do alot of work verifying that the changes my code makes to the DB are actually the ones i expected to happen.  In a current project i am doing against MtGox API, i make trades and then cross check all of the values in my wallet, transaction log and each element of the mtgox completed order record to make sure that the order completely executed (sometimes there are multiple actual transactions that happen to fulfill one mtGox order, and they return the results of each individual transaction).  Being able to PROVE that your system does exactly what it's supposed to do every time while preventing any undesirable changes to the DB via bad data, unexpected values or values out of the range of your normal expected values is very important.

Re: Best swindle in the Bitcoin history? Avalon ASIC's?! = Crisis = Point of view
by

on 12/04/2013, 01:45:32 UTC
But bro, so many BTC's have traded hands that you could buy a million avalons and still not have all of the btc's tied up. I just dont see this math explaining it.

I simply think that BTC is freaking awesome, i am sooo happy that I mined so many back when we were only mining on CPU's

And now all of my freinds are into it and are trying to buy asics and gpu rigs to get in on the action, even if they only mine a fraction of a btc a day.

I use a few BTC here and there but i have some that i keep in reserve for when they are 50 grand plus each, then i will sell. They are from a VERY old block early on in mining.

It's the cross cultural and worldwide excitement over what btc represents that makes it so kickass.

Re: Trust No One

on 09/04/2013, 01:10:14 UTC
Seriously. Don't trust the exchanges, don't trust online wallet services, don't trust your anti-virus software, and don't trust anybody online.

If you absolutely must trust someone with your bitcoins, for the love, choose carefully!

  • Do you know their full name?
  • Do you know where they are located?
  • Have they demonstrated trustworthiness in the past?
  • Are they asking you to trust them? (red flag)
  • Do they have insurance?

Insurance? Impossible, you say. Not so!

When I needed people to trust me to hold bitcoins for a contest, I deposited 50 bitcoins as a bond with a well-respected forum member, so that even if I did something stupid and lost people's money, they would still be reimbursed. You can read about it here: http://bitcointalk.org/index.php?topic=10008.0

Consider carefully who you will trust. With bitcoins, elaborate scams may be profitable. For instance, someone may develop trust for their user name over many months with small transactions on this forum, then take advantage of that trust to make off with a lot of money. Such a scam would only be worth doing on this forum. No other forum in the world would be worth the effort.

If you want someone to hold your bitcoins for you, there are NO online services that have the transparency and security to make me comfortable using them for storing bitcoins for more than a short time in small amounts. The only way to do it is like I did - choose someone whom you believe to be trustworthy, and approach them. If they approach you, or in any way say or insinuate that they are a trustworthy person to hold your coins, STAY AWAY.

If you are thinking that I might not be trustworthy, since I am writing this post about the issue, you are approaching the appropriate level of paranoia.

If you want to store your bitcoins with maximum security, there are lots of resources about how to do it, such as this: https://en.bitcoin.it/wiki/Securing_your_wallet

Here's my summary:

1. Put all your coins in a new wallet that has never connected to the network
2. Encrypt that wallet with the maximum security you can find, using the most secure password you can keep track of
3. Delete the plaintext wallet, and distribute the encrypted wallet to every piece of physical media you own, store it online, and send it to several people you trust

Don't think you can generate and remember a secure enough password? Create a super-long password, and store clues to help you remember it. For instance, your password clue file might say:

My standard password + My throwaway password (backwards, all caps) + &#$%@ + First two sentences of first paragraph of page 19 of my favorite book (include all capitalization and punctuation) + My wife's mother's middle name + My son's favorite superhero + My favorite number times 8734 + food my wife hates (backwards, all caps) + 9-digit number stored with my paper will + 10-character password stored in my safety deposit box + . . . .

You can go on in this way to create as long a password as you want. Store this password clue file with your encrypted wallet, and optionally encrypt both with a simple standard password to keep out snoopers.

In this way, not only can you recover your coins from your "savings account" at a later date, if you get hit by a chicken truck tomorrow and die, your loved ones can probably piece together your password and recover the coins too (better make sure you trust them, and that between them they have or can get the answers to those clues).

I recommend that you practice your wallet encryption and recovery a few times with a small number of coins, until you are very comfortable with the process before you try it with the bulk of your savings.

And remember, this is how most bitcoins services get started:
