Part of the problem is the spectre of 87 million shares out there ready to be sold at any time.

There have always been 100 million shares.  Erik selling 3 million on behalf of a friend doesn't change anything.  Each share you own still gets one 100-millionth of the monthly profits each month.

The representatives of SatoshiDice further warrant that they will never sell more than half the total shares.

Still 37%, no more

Looking at I think is to be the slowest month in history of SD as far as expected profit goes..

Then again, Bitcoins are more expensive now.. But still..

So wait are there 13 million shares owned by the public or 10 million? I was under the impression there are now 13 million, an increase of 30% total shares outstanding.

There have always been 100 million shares owned. 10 million of those were initially released to the public with the remainder held by insiders. A few months (more or less, don't remember exactly) a further 3 million shares were released to the public, making 13 million in the hands of the public and 87 million for insiders. Nothings really changed other than who holds what.

Is there any significant change in the percentage of bitcoin traffic overall that satoshidice accounts for? Increase, decrease? There was a time no too long ago that SD was the topic concerning blockchain space. Since then a lot of new services utilising bitcoin have come onto the chain. Simplistic thought: Either the utility of bitcoin has not really increased or the number of SD players has increased on par. A simple way to gauge increase utility or lack there of. Thoughts?

So you just have to go back through the thread, collect the "Blockchain Tx" and "SatoshiDice Tx" figures indexed by the date posted and you'll have your answer.

I must admit I'm intrigued to see what it will be, so please post the result as soon as you're done.

Nice work!

Now, you just need to plot the USD BTC price (at the dates corresponding to your data points) against each data point, and you'll be able to see what sort correlation exists before you go messing about with linear models.

Similar, but smoother (recalculating the percentage, not using the rounded figure from the reports):

Why would it be important to add USD BTC price to the graph? Do you mean I need to take into account the change in total number of bets placed due to increased stakes caused by BTCUSD? I also graphed the total number of bets and there is a slight hump beginning of year but now back to the usual constant slope. Sure, more $$ a play but same number of TX's. Implying that the Satoshidice TX load has not changed much. Yet despite this one would expect it's share of the blockchain to decrease. Potentially, and based on the first graph, its share is indeed decreasing, very slowly, for the past couple months. Still, this leaves me to wonder about why other forms of utility and services in bitcoin have not displaced satoshidice more.

Probably because you only buy reddit gold once a year, whereas your satoshidice bets cause two transactions each.  I mean the impact on the blockchain per customer is much higher for satoshidice than it is for pretty much any other company.

Sorry, I thought you were implying something in your original post that you weren't - is the change in the percentage of SatoshiDice Tx related to the USDBTC price? I would expect that, since there's a minimum amount of btc that can be bet, as the exchange rate increases the minimum btc bet becomes much higher in terms of fiat and might start to price some players out of the market.

So I'd be expecting a negative correlation between number of SatoshiDice tx and USDBTC price. That recent dip in the percentage of SatoshiDice tx's in the blockchain is rather suggestive.

You could check this, not by adding the price to your chart, but by scatter-plotting the tx as a function of price - the y axis the daily change in number of tx, the x axis the daily change in price. I expect you'd need to do it on a log-log axis , or plot the logs of the daily tx change and daily price change.

I'd do it but I'm in the middle of something else right now. So ....

Agreed. Just comparing to the 2012 percentage and drop from June around 68% share to 55% two months later i would have guessed to see a similar change more recently due to new bitcoin services. I do not remember what changed their share so drastically then (june 2012+) vs now. Anyway, for numerologists and other religions it's interesting perhaps to watch SDice share as a measure of speculation movements vs utility.

So I'd be expecting a negative correlation between number of SatoshiDice tx and USDBTC price. That recent dip in the percentage of SatoshiDice tx's in the blockchain is rather suggestive.

I agree and kind of take this assumption for granted. Though perhaps it would be nice to graph. Always nice to GRAPH!

We are either at or within a day or two of coming up on the one year anniversary of SatoshiDICE.  I see the forum post for it is April 24th, 2012 but the list of secrets goes back to April 17th, 2012.

When was the first real wager on SatoshiDICE placed?

I don't know how to tell what wagers are real, and what are test bets, but the first bet was in block 176627 (2012-04-21 17:02:44) and a bunch more were in block 176629 (2012-04-21 17:28:41).

So I'd say we just passed the first anniversary.

This: https://blockchain.info/tx-index/4228396/1 appears to be the first ever bet.

Despite the absolutely travesty that is their front-end website, it is nice to see S.DICE pulling a profit this month.
