Ok, I figured it out.
The fee setting in options is per kB, I didn't realize that it scaled that way, so when I set it a bit higher to increase my transaction priority (for the health of the network!) it was then requesting ever higher ones at send time.
So now it makes a little more sense.
There's a little more to it than that. Here is a good thread to explain the fees: https://bitcointalk.org/index.php?topic=90500.0 |

In Russia captcha solves you.
Now that was funny ROFL |

but what if you used your own set of html tags like <firstbits>17ocNsU</firstbits>RFKC<bitcoinsarefun>sGarEiqEgzMx</bitcoinsarefun>xS9WnWAmP6P and you can randomly set where they show up and can confuse bots at least Oh, that would be bypassed in less than 1 minute. Yes, 1 minute would be what I would need to program a bot to scrape your personalized tags lol regex included. Even if you randomized them, would all be a matter of training and time. You would be surprised with the bots Russians sell nowadays  ZennoPoster is unstopable  Well, that captcha in the faucet would stop it, but that's one of the few. Any captcha involving text, be it on the page source or on an image is pretty much dead on arrival. You may not believe it, but I've seen captcha systems that involve composing the image from several smaller images: No problem, it screenshots the page and crops the screenshot and sends the part with the captcha to the captcha solving service. The only ones that are trully working are the ones that involving recognizing an object(non-text) between 3 or 4 pictures or, like I said, the one used on the faucet. |

i'd like to send my brother thousands of dollars at a time..so if theres a 12% fee that would kill my pockets..
hmm..
You should use the Bitcoin-OTC then. Maybe it's the best way. Or follow the advice John gave you and get in touch with Tangible Cryptography. The less middleman, the better for you. |

Whats if the amount is in an image format  That would require humans  That would require OCR or a service like de-captcher. Currently most captchas are images and that doesn't stop spammers. At most you would only double the cost to solve it, nothing more. You guys are free to implement it. I'll try and break it and if you want. BTW, the best captchas around are the one that is used on the Bitcoin Faucet(impossible for a bot to solve) and those SolveMedia ones, which may require 2 or 3 tries, but eventually will be solved. What if you show a full address but highlight the letters and numbers randomly ? It would be an actual working address and the amount to bypass it would be in a pic too. If you use html to higlight the letters and numbers it can and will be detected by more advanced bots. If you use a picture to show the full address, nobody will have the guts to write it and send the coin lol |

Step-mother against crypto currencies? lol At any rate, your flow might look something like this: 1.) Download and install bitcoin client 2.) Make Mt.Gox ( www.mtgox.com) account 3.) Choose to deposit cash via BitInstant 4.) Make BitInstant account 5.) Choose deposit method 6.) Deposit Cash at WalMart/whatever location you want 7.) Buy BTC with deposited money 8.) Send BTC to your brother 9.) Have your brother buy a prepaid credit card or something similar online with his BTC you sent him. He would be better of just sending him the money with paypal... After all that he would have lost at least 12% of his money. I thought that it would be 3.99% or what Bitinstant charges you? Alternatively, just get hold of one of those bitcoin sellers like TangibleCryptography who allows you to buy bitcoins with a simple cash deposit. Check the Currency Exchange subforum for more information. And MtGox fees? And what about the guy who would sell the prepaid credit card to his brother? lol It adds up |

Those high fees are anti-spam measures, and from your description, that's what you've been doing: spamming the network playing SatoshiDice The different address for the change and it being hidden from the "Receive Coins" list is part of the protocol, and it's there to improve on anonymity, nothing's broken. Maybe you should give a read to http://bitcoin.org/bitcoin.pdf and https://en.bitcoin.it/wiki/Main_Page before complaining about the way the protocol is designed |

What's the diference between that and just grabbing 5 or 6 random letters/numbers?
You cant pay a normal captcha instead of solving it Sometimes they are so difficult to solve I just want to tip them a satoshi to let me use the friggin site! Yes, you can pay a normal captcha... http://de-captcher.com is just one of the dozens of sites that have OCR and human solving available for as much as $2 for 1000 captcha solutions. Oh i get it : pay this tiny amount to signup and to prove your not a bot
That will not prove you're not a bot as any bot can do that. Scraping the page to see which amount to send to which address and sending a json-RPC command to bitcoind isn't that difficult. |

Aquatic Ape Hypothesis?
Damn, you're the first person I find that knows about that theory. I used to mention it to my friends, but after doing it 4 or 5 times and "get the look" I stopped  EDIT: And cbeast also knows it. What I find particularly interesting in that theory is the explanation for why the human brain evolved so much. |

What if you took bitcoin address and turned them into firstbits style addresses and displayed them and users need to enter that correctly as the captcha ?
Can you display only parts of bitcoin addresses in this way programatically ?
What's the diference between that and just grabbing 5 or 6 random letters/numbers? |

Maybe it's time for the free market everyone talks about to work it's magic . Yeah, victims and/or charities should pay people to compile the evidence. I certainly don't expect forum moderators to do these investigations. But... how will those third parties have access to certain information, like IP addresses? Isn't there potential for abuse in case you give those records to "external investigators" who ask for them? Or did I misunderstood what you meant? |

Right now, transferring Bitcoins pretty much requires a PhD, or something close to it.  That can't be true as the closest I've ever been to a campus was while going to college parties and I use Bitcoin every day lol |

Stop trying to find solution for non-existant problems, dudes...
From my 49 referrals, 35 deposited. Where are the ones that click links and open accounts to invalidate referral links then?
FFS...

Theres a $100 000 buy order at btc-e.com
Good lord! Lol  $85k at $6.55 |

I also wonder about chargebacks if they link to bank accounts.. They'll just conclude sooner or later that they'll need to charge more than 0,5% to cover for fraud |
