Yet another martingale bot for SatoshiDice (Java app)

[Come-from-Beyond]

It's a Java application. Requires http://code.google.com/p/json-simple/ to build and parse JSON.

Code:

// (c) 2012 Come-from-Beyond

import java.io.InputStream;
import java.io.OutputStream;
import java.net.Authenticator;
import java.net.HttpURLConnection;
import java.net.PasswordAuthentication;
import java.net.URL;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.JSONValue;

public final class SDMB
{
	public static void main(String[] args)
	{
		try
		{
			Authenticator.setDefault(new Authenticator()
				{
					protected PasswordAuthentication getPasswordAuthentication()
					{
						return new PasswordAuthentication ("username", "password".toCharArray());
					}
				});
			
			while (true)
			{
				double bet=((double)(balance(1)/135))/100000000;
				if (bet<0.01)
				{
					Thread.sleep(1000);
					continue;
				}
				for (int i=0; i<7; i++)
				{
					final long balance1=balance(0);
					
					final JSONObject request=new JSONObject();
					request.put("method", "sendtoaddress");
					final JSONArray params;
					(params=new JSONArray()).add("1dice8EMZmqKvrGE4Qc9bUFf9PX3xaYDp");
					params.add(bet);
					request.put("params", params);
					sendRequest(request);
					
					final long balance2=balance(0);
					
					long balance3;
					do
					{
						Thread.sleep(1000);
					} while ((balance3=balance(0))<=balance2);
					
					if (balance3>=balance1) break;
					
					bet=bet+bet;
				}
			}
		}
		catch (final Exception e)
		{
			System.out.println(e.toString());
		}
	}
	
	public static JSONObject sendRequest(final JSONObject request) throws Exception
	{
		final HttpURLConnection connection;
		(connection=(HttpURLConnection)(new URL("http://localhost:9876")).openConnection()).setRequestMethod("POST");
		connection.setDoOutput(true);
		connection.connect();
		final OutputStream outputStream;
		(outputStream=connection.getOutputStream()).write(request.toJSONString().getBytes("UTF-8"));
		outputStream.close();
		
		final InputStream inputStream=connection.getInputStream();
		final byte[] response=new byte[65536];
		int ptr=0;
		int numberOfBytes;
		do
		{
			if ((numberOfBytes=inputStream.read(response, ptr, 65536-ptr))>=0) ptr+=numberOfBytes;
		} while (numberOfBytes>=0);
		inputStream.close();
		
		connection.disconnect();
		
		return (JSONObject)JSONValue.parse(new String(response, 0, ptr, "UTF-8"));
	}
	
	public static long balance(final int numberOfConfirmations) throws Exception
	{
		final JSONObject request=new JSONObject();
		request.put("method", "listaccounts");
		final JSONArray params;
		(params=new JSONArray()).add(numberOfConfirmations);
		request.put("params", params);
		return (long)(((Double)((JSONObject)sendRequest(request).get("result")).get("")).doubleValue()*100000000);
	}
}

It starts with 1/128 of current confirmed balance as an initial bet and then double amount if lose. I divide by 135, not 128, to have some BTC for tx fees:

double bet=((double)(balance(1)/135))/100000000;

if (bet<0.01)

...is used to avoid too low bets.

I tested it on 2000 bets using "lessthen 32000". Went from 0 BTC to 14 BTC and back to 0 BTC. At the beginning I used my own bitcoins which were removed from the capital when I got 10 BTC from SatoshiDice. After my bitcoin-qt.exe had reached 1500 thx it started to lag much. After 2000 thx I became bored and made a couple of big bets manually until I lost all won money. Nothing surprising, but at least miners earned 1 BTC as fees.

NB: In the long run SatoshiDice wins so don't miss a right moment to stop.

I decided to add a compiled version of the bot for those who r unfamiliar with Java: http://www.4shared.com/file/UeCqpEXa/MartinBot.html

How to use
1. Download and install Java Runtime Environment 7 (JRE): http://www.oracle.com/technetwork/java/javase/downloads/index.html
2. Launch bitcoin-qt.exe in server mode:

Code:

bitcoin-qt.exe -server -rpcport=9876 -rpcuser=MYUSERNAME -rpcpassword=MYPASSWORD -rpcallowip=127.0.0.1

3. Launch the bot:

Code:

java -cp MartinBot.jar MartinBot http://127.0.0.1:9876 MYUSERNAME MYPASSWORD 1dice8EMZmqKvrGE4Qc9bUFf9PX3xaYDp 0.1 2.0

Last 2 parameters are starting bet (0.1) and quotient (2.0) for next bets in case of loss.

To stop the bot press [CTRL]+[C].

nice job, maybe build some random delays into the bot,
could help to win more

[22bones]

Nice work.  I ran a slightly modified version of this just now, and eventually ran out of coins when it lost the 'less than 32000' game 14 times in a row! (on btcdice.com)  Only lost a small amount of BTC but it was fun.

[Come-from-Beyond]

it lost the 'less than 32000' game 14 times in a row!

WOW!

[Gyrsur]

please don't play this all in any way. no chance at all. prevent loss from newbies.

[Come-from-Beyond]

The chance is above 0, the key point is to leave the game at the right moment. Just to prove it I played SatoshiDice with Martingale tactics while watching Red Bull Stratos. I used 10 spare bitcoins and got 20 bitcoins back - https://blockchain.info/address/1CDoCox8dX9SRzxwRRxLRTsFJ2b4XThYvX.

In addition, you will probably lose everything if you went on.

But thanks for making the bot - gambling it NOT A WAY TO GET BITCOINS, it's for entertainment.

[squid]

great, i'll have to throw away some money later

Here is my preset for this bot. Works much better than mining. About 0.5 BTC per hour with minimal risk. 

java -cp MartinBot.jar MartinBot http://127.0.0.1:9876 LOGIN PASSWORD 1dice8EMZmqKvrGE4Qc9bUFf9PX3xaYDp 0.003 3.3

Attempted to test it but kept getting

Code:

java.net.ConnectException: Connection refused: connect

Have u launched bitcoin-qt.exe this way:

Code:

bitcoin-qt.exe -server -rpcport=9876 -rpcuser=MYUSERNAME -rpcpassword=MYPASSWORD -rpcallowip=127.0.0.1

?

[jasinlee]

Yeah it worked without error after I made th .conf . Just the java is fighting me.

Unfortunatelly, I have to work on ur computer to find the issue. Check firewall settings, I use MartinBot.jar by myself without any problems.

Actually, if you configure it correctly, you are muck more likely to win than to lose. The problem is, if you do lose, you lose much, much more than you tried to win.

It's like a reverse lottery where 99.9% of the people get $1. But one out of 1,000 people get tortured to death. Of course, your "expected profit" is negative. However, you are more likely to win than to lose.

I use such a strategy:

In the morning I deposit 10 BTC and launch the bot.
In the evening I shut the bot down.


Sometimes I see 0 BTC on the balance, but in most cases there are like 20 BTC.

java -cp MartinBot.jar MartinBot http://127.0.0.1:9876 LOGIN PASSWORD 1dice8EMZmqKvrGE4Qc9bUFf9PX3xaYDp 0.003 3.3

Is that right? Was that 0.5 BTC per hour a typo?


I plan to use these settings below as was suggested above:

java -cp MartinBot.jar MartinBot http://127.0.0.1:9876 LOGIN PASSWORD 1dice8EMZmqKvrGE4Qc9bUFf9PX3xaYDp 0.003 3.3

Does this look good or would you all suggest better presets?


Thanks for the app. I was going to use the martingale R app posted in the "How to Last Longer Thread" but I like the automated functionality of your bot better.

Yep. Absolutely.

If you specifically configure it for double or nothing, you are much better off just placing a single bet. The Martingale strategy only works if you are trying to win an amount much smaller than the total amount you have to bet.

[Gilboa]

Is the bot supposed to run continuously? After a loss the bot doesn't do anything. It also only submits a second bet if there's a win. I have 5 BTC in my wallet so that might be to low?
