I just received an email from someone telling me they bought a new phone and so lost access to google auth, and so can't log in.

They want me to reset their google auth so they can log in again.

This seems wrong to me.  If I reset google auth on demand, what's the point of even offering it?

So please, make sure you have a backup of your google auth secret, in case you ever buy a new phone and so lose access.  If you already have google auth enabled on your account but don't have a backup of the secret, please PM me and I'll temporarily disable it so you can make a backup.
Seems like a good solution would be to have them send you a verified message from a bitcoin address where they had previous sent a large deposit.  If they have an email registered with the account, sending an email from that account would seem like another good idea to verify identity.

I once lost GA code to my account at MtGox. They have reset it without any problem. Just an e-mail was sent to my e-mail address (stored in their DB) mentioning that the GA will be reset in 3 weeks time and if I didn't requested this I should contact their support team. Another e-mail was sent again like 3 days before reset date. Something similar could be done for JD.

seems like needlessly complicated.
after all, if you know your math, you know that just betting less it as effective as doing that.

remember we are here to service the users, not to con them.

if JD is completely open about the math, and there is still a demand..... it seems no different than the current implementation of JD. doog is completely open about the math, and there is still a demand for the site.

let the user determine what is best for them.

additionally, insurance could be another revenue stream for doog, and reduce the variance in his income as well.

also, i think a side benefit would be to encourage people to YOLO more often if they could be sure that they arent going to lose their shirts doing it.

it would create a good show if nothing else.

nope:

1) if insuring was free, then implementing it would be a waste

2) if it had a cost, it would be a disservice to users: a way to con them into giving us more money without real benefits

3) if we did it anyway, we might end up into a paradox where if a user loses (x-1) times in a row, it's better for him to lose his next bet than to win it

For point 3, since the game is "random", a user cannot intentionally cause a loss.

im not clear on what you mean with number 1. do you mean the house pays out the same as expected losses with no fee on top? that wouldnt be any different that allowing people to place 0btc bets, right? and people do that all the time.

it appears as if your 2nd point applies to JD as a whole as well. it has a negative expected value, it benefits some and costs others, the math is explained completely, and its all just for fun anyway. insurance is the exact same thing. As far as benefits, thats up to the user to decide for themselves.

there may be times when people benefit more if they lose the next bet, but isnt that kinda a cool scenario? sometime people are trying to win on the next roll and sometime they are trying to lose...that sounds really fun and interesting to me. either way, they dont have control over the roll, so whats the difference?

I made some simple calculations to find how many bets (of the same size) you need
to be 95%-confident that the house is positive, on the 1% edge.
And it's around 15000.

on JD of course bets are of unequal (and dependent) sizes, but only big ones are relevant.
So if  whales come and start making those 300+ rolls, they better make at least 15000 of them.

Gives you an idea of how long-term your investment should be.

95% = 2 SD

I can do 15000 rolls of the same size. (what i've been doing lately, actually)... I just gave 10 BTC profit to the site a couple days ago, but I intend to take that back. hehehe. (disclaimer: Dabs is not an investor at the moment.)

Doing 15000 rolls of the same size and chance has an expected value that is 15000 times that of a single roll.

So unless you found a single roll with a positive expectation, this doesn't sound like a good idea.

Magic and dragons would also work, just FYI.

I realize Just-dice has a lot of variance, and I'm not going to be upset with the site if I log in for a monthly review and see at a glance that my 0.14 BTC invested is down 0.001 at the moment (for example), but I very well might get upset if I have to do several minutes of calculations just to find that out.

Just to be clear, are you happy with what's currently shown?
Yes, I am. In the case of Just-dice, I know how much I put in originally, so as long as I can see at a glance the current value of my investment I am happy, and the (profit) column is a nice extra to aid in figuring out my profitibility at a glance without needing to do any calculations myself, especially if at some point in the future I forget or lose my records of how much I invested. I have a longer wish list for exchanges like bitfunder, etc. with more than one asset (in which case, I want them to automatically total the value of all my different assets for me so that I don't have to do it manually), but since just-dice basically is just one asset, that keeps it simple.

Congratulations on producing a great site! Keep up the good work! And congratulations also on your resolution for that issue that came up a week or so ago--I would have hated to see you get frustrated because of that and lose interest in maintaining the site. In the future, if there is ever any kind of glitch and my account gets credited with anything it wasn't supposed to, please don't hesitate to roll back the transaction. I'm sure my bank would do the same without any second thoughts.

I need to get some dung beetles. They might know the outcome of the next roll.. magic seeds, dragon babies, and dung beetles watching the milky way galaxy.

used the site yesterday, pretty fun and pretty fast.

only bad thing was no day spa, you lose 200 btc in 60 seconds you expect a day spa!!   Wink

hehe just kidding, best of luck all.

I wonder if there would be any interest in a "high roller" version of the site where the house edge is 5%, but all big players get shipped luxury items for playing.  Smiley
