1  Economy / Auctions / Signature space for rent :: Legendary user :: 80+ quality posts a month on: November 24, 2017, 09:56:42 PM
My signature space is open for auction.

My account has high Trust, check my posts for quality and dispersion through sub-forums, you will be more than satisfied.

Auction rules are:
- starting bid is 0.03 BTC/month
- bid increase is 0.005 BTC
- no scams, no NSFW content.
- If you win the auction, your content would be in the signature for a month starting the day you make a payment to an escrow of your choice from the Bitcointalk Escrows list: https://bitcointalk.org/index.php?topic=855778.0. Payment must be max three days after auction ends, and stays in escrow until the arrangement is over.
- only Members+ accounts can bid, or accounts that already run some other signature campaign. All other bids will be invalid.
- bidding is open for one week, until December 1st, 23:59:59 UTC.

Happy bidding!
2  Bitcoin / Development & Technical Discussion / Pure Python ECDSA implementation? on: January 26, 2014, 10:59:42 PM
Is there a pure Python ECDSA Secp256k1 implementation? I don't care how slow it is, because calling libcrypto in a loop gives me Segmentation fault every 3-4 million loops. I'm using Joric/bitcoin-dev implementation and I've tried to find the cause with gdb, but give up on it, have no more nerves for it.

Using some utility through RPC is not an attractive option because of overhead. If anyone has a link to a native Python solution I would be grateful.
3  Bitcoin / Mining / Historical mining calculator? on: October 25, 2013, 12:15:05 AM
Is there any software/site where you can enter two dates in the past + hashrate, and get the result how many BTC was mined in the period between these two dates?

5  Economy / Digital goods / [WTB] BTC/BTC-E for Zynga Poker (Facebook poker) on: July 14, 2013, 12:37:34 PM
I'm buying BTC, paying in Zynga Poker $, world's most popular poker game, played by 6+ million daily users.

Please don't ask for a small amount of Zynga $, you have to convince me to deal under 100.000.000$.

Give your offer and I'll respond quickly. Happy biding and playing poker!
6  Economy / Service Discussion / BitBet.us nonsense, avoid using the site until you realize how they operate on: July 08, 2013, 11:40:42 AM
Just to let the community know the facts:

I decided to try BitBet.us, put in 0.02 BTC just for the fun of it. I've chosen a bet about BTC difficulty, more than a week before closing while the result was far from obvious, in fact there was one much bigger bet on opposite outcome after mine.

Bet details:
http://bitbet.us/bet/454/btc-network-difficulty-tops-25-million-by-end/

Bet TX id:
https://blockchain.info/tx/e28963e5183ccf2c13ffbb3e41857ccaf53b1a6679d3453c5772b6d65786f7c6

It was fairly balanced bet, 124.78 BTC on winning side and 43.58 BTC on losing side, Weighted Winning: 2`891`58, Weighted Losing: 2`568`92.

Still, BitBet.us calculated:
BTC IN: 0.01966650, BTC OUT: 0.01954554

I won that bet, and got less money than I've put in?!? What kind of nonsense is that?!?

If you can win a bet and lose money on balanced bet long before closing, think what would happen on late unbalanced bet.

Of course, I've sent an email to BitBet.us a week ago, asking politely for clarification, guess if I got any answer from them. You guessed right. Avoid BitBet.us in a big circle.
