***EDIT 2012-10-28 1,000,000 processed bets promotion! Fees lowered to 0.10% house edge, giving 99.90% expected return per iteration!***

Bouncing dice off the blockchain is fun and all, but what if you need to do it 10 times to get your fix? Sadly, this still isn't enough for some of us.

Introducing DiceOnCrack.com, which allows you to throw up to hundreds, thousands, tens of thousands of throws with a single deposit! DiceOnCrack.com simulates the first throw in traditional fashion, but subsequent throws are the hash of the previous throw. This allows for an infinite amount of provably fair throws.

DiceOnCrack.com offers different strategies, each one customizable. Please visit http://diceoncrack.com/howtoplay on the site to find out the exact details.

Customization is done with the last 4 satoshi places on deposit and include:
Threshold - you pick what level to define a win.
Exit Point - Choose the level (relative to deposit) in which wagering is stopped and balance is returned.

And the strategies include:

Simple:
An initial deposit is split into 0.001 BTC wagers, and bet up to 15,000 times. The default win threshold is 'less than 32,000', and an exit point of 2x deposit. Each iteration has a 99.50% expected return to keep the good stuff in your system longer.


Martingale:
Let DiceOnCrack.com do the work for you! Each throw aims to make 0.001 BTC. If unsuccessful, the next wager is increased just enough to "get you back to normal". If the remaining balance isn't enough, the balance will keep being wagered in its entirety until "you are normal" again. All martingales have a 99.50% expected return per iteration.


Martingale - [BUSTO]
Same as the Martingale strategy, however after it is impossible to get back to normal, a new, lower level is set as "normal"

Martingale - [EXIT]
Same as martingale, but when the balance is not sufficient to get back on track, the balance is returned.

elagnitraM
The reverse martingale. Keep wagering 0.001, but each win is bet in its entirety until the exit level is reached.


Minefield - Avoid the mines!
Something different. You need to make 1000 steps through a field. With each step, there is a 99.93% chance of safety. Make it all the way through to return 1.998x deposit! This is customizable, and each step can be made up to 99.994% safe.


2012-10-24: BETA TESTING PHASE. Caps are low. At this point DiceOnCrack.com will not handle any balance higher than 10.000 btc. DiceOnCrack.com will also not allow the balance to get that large. If a wager on any iteration has the potential to violate this, the balance at the time is returned without processing the wager. Please watch the website for an "offline" status. While offline, deposits will not be processed, and returned with our refund policy (basically, you pay fees if necessary).

Caution: DiceOnCrack causes euphoria, loss of appetite, insomnia, increased heart rate, increased blood pressure, and ultimately a craving for more DiceOnCrack!

Ok, who got bitcoin on the obverse and Pirate on the reverse?

Data please.

I do like much more now, thank! Nice work.

I am a fan of the service, works well. Congrats.

You can charge what you wish, but it is a bit pricey for my wallet. I'd probably spend more overall if prices were cheaper.

I have been playing with this all day. Very cool.

Question: Why hasn't anyone used this for Escrow? I bet there has to be a page on this somewhere

Example:
* Seller goes to Escrow-BTC.com and signs a message from address 1EwMryEWqFLrfyyK6gTz3HUwgmLsVTFuQr (proves he knows the private key, not on-line wallet)
* Escrow-BTC.com then generates a vanity address with that public key and sends Buyer a PrivkeyPart: 5KiThyF8KKXm51jRT99Yckn63hGXFsBjniQNdYqyqDvhSHvQmEB
* This produces a vanity address: 1ZZZZKnrZRAmCgfVtjpgzZc1f9SkfndF5, which buyer sends funds to.
* At this point, no one knows the Private Key to 1ZZZZKnrZRAmCgfVtjpgzZc1f9SkfndF5
* Seller has delivered package, buyer can release his PrivkeyPart to seller. Buyer can only not deliver funds out of spite.
* Seller combines his private key with buyer's PrivkeyPart:


And viola! The seller has access to funds.

Where can I get keyconv for windows? I can't find it.

sorry, nevermind. Didn't see it in .21. Got it from .20.

If I understand correctly, you will have 2 private keys (5J... and 5H... for example) combined to make a 3rd private key (5K...).

Could you send 0.10 BTC to the first address (5J...) and 0.10 to the 2nd (5H...) but send 100 btc to the 3rd (5K...)

Set up to be notified when one of the first 2 addresses are drained, this lets you know you have been compromised on 1 system.

In the CPU mining days when GPU software was just being developed, there wasn't much talk of the price going down, or that it would be bad for bitcoin. Why is it different this time?

Headwind is the currency risk. If you expect bitcoin to rise to $100/coin over the next few years, it will be difficult to justify a purchase of 5000 btc today.

This is the system I would try to create. Make 3 of 7 scheme. 7 sets of 200 QR codes that each reveal a private key. Keep 1 in the house, 1 in SD box and 1 encrypted on dropbox. The other 4 carefully distributed among friends & family (who are not familiar with the others). Don't tell them who else has codes. You can give a set to a relatively trusted forum member. If you ever die or get in trouble, your friends and family will start asking around.

Bonus: Make a deterministic wallet, and engrave 1/2 of the seed on a mountain in Las Vegas, the other on a large rock in Minnesota.

Thank you.

By random, I mean not predictable. I ask because SatoshiDice takes the hash of a txid. Would it be possible for someone to calculate the id (or part of an ID) before sending? Why doesn't SD just use the txid?

I suggest that the premium is due to the real interest rate for bitcoins. There is no Federal Reserve keeping rates artificially low, and the cheapest people can 'borrow' today for bitcoins is 50%/year.

Back up!

I keep getting:


when attempting to use SSSS creating a (3,7) scheme for a 51 character private key. Sometimes the scheme is created immediately, and sometimes it takes minutes to create. Is this error why it sometimes takes so long to create? I want to create 50 schemes, so it would take all night.

How to fix? Is there some .conf file I need to address, or do I need to edit the code of SSSS? I'm not an expert at linux or coding.

There were 10's of thousands under 7 cents each. Price would rally to 8 cents, back to 6.5 cents. The few people mining back then were piling them up, why not take $700 and sell 10,000 of "nothing".

I have pieced together a name and address from return labels, and according to google, the name and location exist. Did HeavyMetal (scammer) use his neighbor's name or some random address in the phone book? Quite possibly. However he did successfully send me an insured package international (Canada to US) and declare a $1,000+ value. Not sure how he would have claimed insurance if names and addresses didn't match.

If you're good at tracking down people or just want to do some googling yourself, PM or email me at auto31524412 at hushmail.com for his name and address. Include a btc address for any reward payment. If it turns out it is this guy, I can weigh my legal/non-legal choices.

HeavyMetal's early out: refund 447 coins (75%) to this address: 16Hc9LVLrAX3uRudAXAn6iccPEjcheCYoc and I will drop this. I am giving away 33% of what I receive at this address to those who have helped in any way.

I grew up playing Sim City. When the people complained about the traffic, I got rid of the roads. Problem solved.

Possible / practical?

Keep coins in 20 addresses. Have remote online computer monitor those addresses. if 1 of 20 addresses has a withdraw, move all coins in the other 19 to panic address.
