SERVICE ANNOUNCEMENT: We've had to temporarily disable the deposit bonus to fix some issues. We don't anticipate this feature being down for a long time. We can update you once this feature has been restored.

Thanks for your patience!

Noted.

I also wanted to ask if rewardpoints are accumulated as normal even if the deposit bonus is activated?

yes, they are. or rather they were, since bonus is disabled now.

hi guys,

so i wanted to try some different strategies for the HI-LO game, but the auto-bet does not have all the features i need (like reducing the bet or increasing/decreasing multiplier by X%). I also noticed that there are quite some amount of JS scripts out there. with such a script i could automate my betting strategy, so i wanted to ask if it is legitimate to use something like that?

also can i create multiple accounts just for the HI-LO game, if i only use the faucet on my main account?

Whats the purpose of creating muli account for Hi-Lo Games, theres no benefits since you cant claim freeBTC on those account to play on Hi-Lo Game. due to IP, Your IP can only claim once every 60 minutes, even if you create another account you cant claim freeBTC, using proxy is another story, and its not allowed and against its rules.

i want to use different strategies per account, so they dont mix up in the history. When i use both strategies one after another in the same account, i will only see the stats of a mix of both strategies.

The lottery round will be provably fair from the round starting today (round 110). The SHA256 hash for the server seed of this round will be b09379ba8c6f0e995b623d118ec1836ee3c92f3085c025a2ee100ce1e10c3806. Someone please quote this so that I cannot edit it later. The full details on how the winners will be picked will be updated in the website shortly after the new round begins.

The 1 BTC bounty for helping with ideas for developing this system will be shared equally between Zhor and edge777. If you guys see this message, please pm me your Freebitco.in user id's. If not, i'll contact you in a couple of days to ask for them.

This post describes how the winners will be picked: https://bitcointalk.org/index.php?topic=320959.msg19748669#msg19748669

I shall try to pre-generate the seeds for the next 1,000 rounds and post their hashes in the forum after the first couple of provably fair rounds have completed successfully.

well guys, i can confirm that i just received the 0.5btc reward. Thanks, wetsuit!
Can you make screenshot?

i would love to do that, but i dont know how, since my balance was simply updated to +0.5BTC. There is no "proof" that i could show you.

I have been told not to gamble but this site looks amazing or may be im gonna get greedy about the money. Hi-lo is said to be provavly fair game but is it really the case.  Has anyone im this forum won some bih prizes?  Im reading all the neg replies in here which tell me not to gamble.  But one must try everything out there so i will give it a chance.  Hope to earn big bucks at least with little luck. 


They say it is probably fair the game but you can look in your eyes when you are on auto but  you know that there is manipulation form the inside. 1st you would analyse that you win it win it win it when that is enough suddenly it would be loss loss loss on this because E.I is on the game now if he sees that you pretty good player they will drop your algorithm and starting the balance to became 0

i think you are totally right about your claim that when you are on auto play sooner or later the algorithm switches its mode if you won too often and it produces loss after loss till your balance is 0 (or almost 0).  Sad

i think the possibility that you lose 18 times in a row at chances of 50/50 per roll are pretty low - even tho there is a very tiny chance for that to happen.

strangely it only happens when you've won too much in multiply btc in 1 or 2 days. well time to stop gambling ..  Wink

  Cry

this is impossible. you can prove the fairness of each and every single roll. there is no manipulation possible (with reasonable effort) to "just change the algorithm". I can say that with confidence because the site describes the algorithm used to provide the 0-10000 number very detailed. You could even randomize the client-seed before each roll. I repeat just once more: there is no way the server could cheat you.

all this talk about the unfair lottery... Wetsuit is trying to make this lottery provably fair. The fact that he is trying to implement this makes it very plausible that the lottery until now was fair, but just unable to prove its fairness.

to show my support in the system i went ahead and bought a million tickets. Let's hope for my ~5% chance.


Also, as a sidenode, this catapulted my bonus to the max:



Just one with 1M tickets
5
4361133
0.17267040 BTC
1,042,743

Are you that lucky person?

nope, thats not me. i also had over 1.1 mil tickets, this guy has just 1.05

Unable to Understand the concept of  This following shown in my account

Bonus +0.00000962 BTC added to all rewards!

Play MULTIPLY BTC or buy lottery tickets to increase your FREE BTC rewards by up to +0.00001406 BTC

88.3229% achieved towards the next +0.00000074 BTC bonus!


For anyone who is interested in numbers and percentages:
For me it takes a multiplier bet of about 86700 satoshis to get a full 1% increase towards the next bonus level.
Accumulating this to 100% would of course be a bet of 86,700,000 satoshis. If i play it "safe" (many small bets) i can safely assume to lose 5% of that which would be 4,335,000.
now that 100% means that my bonus will increase one stage, which is currently an increase of 76 satoshis.
Just right now i get 912 satoshis bonus per roll and lose about 3% progression with each roll. that means i will have gathered about ~30k satoshis only from the bonus while losing exactly 100% progression towards the next tier.

So for losing about 4.3 mil satoshis i get 30k satoshis back from freebitco which is about 0.7% of my losses. Not too much, but still i wanna say thank you to the admin for this, since it does count all your past multiply-games.

Also be aware that i do not fully understand the system and these numbers may vary for your account.

Holy Sh*t, we've already commenced a HUGE Rewards Points bonus weekend >>>>> 3x Rewards Points starts tonight!

For the entire week, we'll pay you 6 Rewards Points for a free roll, 3 Rewards Points for a multiply roll activity exceeding 1500 satoshi, and 3 Rewards Points for a referral roll!

Follow us on Twitter to get more announcements of great promotions > https://twitter.com/freebitco

i think you meant weekend.

Sorry about the delay with this, I have just gone through all the lottery drawing ideas and this is the best one I found mainly because I don't have to store 200 million+ ticket numbers for each round and the "window" system for picking winners is what I already use.

I have a few modifications to this idea though to make it easier to verify and implement. So, this is how the lottery will work with my modifications:

1) Before a lottery round starts, a server seed will be generated and it's hash will be provided.
2) After a lottery round is concluded, a list of user id's and tickets will be produced in a text file ordered by ascending user id's. This order will be used to create the "ticket-windows" as Zhor and edge777 have described below.
3) Then a tweet will be made to our twitter account containing the following:

  • A future bitcoin block number that has not yet been mined. The block hash of this block will be used as the client seed. This block will be at least 3 blocks in the future.
  • The link to the text file in 2.
  • A MD5 hash of the text file in 2 to verify that the contents of the text file have not been modified since posting. If the contents of the file change, it will produce a different MD5 hash which will not match the one provided originally.

Twitter is ideal for this because it will provide a timestamp that can be verified to check that the block number provided is in the future. Also, tweets cannot be edited, only deleted so if I delete the original tweet and post a new one after the block has been mined, it will have a timestamp greater than the timestamp of the block used for the client seed.

4) The server seed, block hash and an incrementing nonce will be used to draw the 10 lottery winners.

Please let me know if this can be exploited in any way or if it needs clarification. I believe this is the easiest implementation that can also be verified quickly by users. I am still open to ideas until I proceed with implementing this (in the next few weeks) so please post your ideas and if something better comes along, I'll use that. If not, the reward will be divided equally between edge77 and Zhor.

The original idea is below.

well, hello everybody from bitcointalk,
[...]

hey, nice to see that you liked my idea!
I still don't like the usage of 3rd parties, but at least it will hopefully bring more people to your twitter page. Let's just assume that it is impossible to bribe twitter to change a tweet.
I like how it is much easier to verify, but it is on the cost of privacy. Over the weeks, everyone can analyze the "basic activity" (seen as the amount of tickets a user spent on the lottery) of individual users and of the system as a whole. Also - and this could hurt more - you will publish indirectly the number of inactive users. And you can also see how long it takes for any user (in special or in general) to go inactive.
However i dont see any way to manipulate the system as user or admin.

You also need to publish the exact algorithm how the 10 lottery winners are calculated.

Ok, lots of questions on the new bonus - I have answers!

The bonus is granted on Free BTC rolls. To be eligible for the bonus you need to participate in some Multiply BTC rolls and/or buy lottery tickets. On your Free BTC screen (sample below) you'll see what your progression % is toward achieve bonus eligibility and the amount of satoshi the bonus is worth. In the sample below this user is 9+% toward achieving the bonus, once that number gets to 100% they can claim the bonus on their next Free BTC roll.

The size of the bonus ranges from the base Free BTC roll to 19x that number (also shown as the higher number on the screenshot below). The more you achieve the bonus the greater your chances are of getting a higher payout.

Anyone achieve 100% yet? Let's see some screenshots!


I guess i already played enough hi-lo. How long will this bonus last?

LUCKY NUMBER            PAYOUT
0 - 9885              ----->0.00002280 BTC
9886 - 9985         ----->0.00002205 BTC
This is mine in freebitco.in. Can anyone explain why?







1MtEaqRv2NzoEUV549eRErGBgtFioHEk7b

you probably took the 1000% bonus paid with 3600 RewardPoints. This bonus is only for the 0-9885 payout, which is increased by 1000%. This effectively increses it to 11x, while the next tier is only 10x and it does not get amplified by the bonus.

***The following is my updated algorithm for determining the lottery winners***



Ok, so this uses your already provably fair method for determining rolls.
----------------------------------------------------

At the start of the round, have the server create a seed, and display that seed hashed to the public on the lottery page. At the end of the round, automatically post an excel spreadsheet to Dropbox (I believe they have an API) showing the acquired tickets for the round and who they belong to (like this: https://docs.google.com/spreadsheets/d/16FCMiXgVXI9unoFMm2qgCoK7gGA5BaZqth2BCoddT7k/edit?usp=sharing). Posting the file to Dropbox leaves an upload timestamp created by a server INDEPENDENT of freebitco.in, meaning the file cannot be tampered with or it would be evident in the timestamp.

[...]


using such a spreadsheet in Dropbox does have some big disadvantages (in my opinion):

a) the size of file can get gigantic:
imagine tons of entries with just 1 or 2 tickets (from free rolls). lets calculate. 8 byte for timestamp, 4 byte for userID, 8 byte for ticket window (2 integers) makes a total of 20 bytes for possibly each ticket. say that we have only entries with 2 tickets, that would mean we could have 50 million entries in the spreadsheet. That is around 1 Gigabyte of Data. This will also grow with more active users. Also it gets very messy and confusing to quickly find the winning ticket number.

b) you are relying on 3rd parties
Using dropbox (or any other "trustworthy" partner) is always a risk for freebitco. If dropbox is not available, we cannot draw lottery winners. Are we willing to risk that? What if dropbox changes their services, APIs, or financial plans?

c) you are publishing sensitive data
publishing the exact date and amount of aquired tickets combined with the userID they belong to will reveal many other things as well. Now everybody can track specific users, check when they received tickets (and with that, they can backtrace the action you did (playing free rolls? 2 tickets. 100k tickets? probably bought directly. 12489 tickets? oh, you probably bet 12489*1500 (current rate) = 18,773,000 satoshis in high-lo game. Now you can also see a users Referer, since he will also receive 1 ticket at the same time you receive 2 from a free roll. With the timestamp you can now find out at which times of the day a user is active which will be an indicator of his timezone. This is a leak of personal data many people should be concerned of.
18  Economy / Gambling / Re: FreeBitco.in - Win free Bitcoins every hour! on: June 16, 2017, 08:20:49 AM
so i mean:

say there is a number x (lets set this to 1 million, but i dont know the exact number, im just guessing)
if you bet 1 million satoshis in the multiply game, freebitco wins 5% (house edge) ON AVERAGE. That would be 50,000 satoshis loss for you.
from those 50,000 satoshis they could give you back maybe 5,000 (again, just guessing) through this bonus. so they would activate your bonus until you have collected 5,000 satoshis. then your bonus would drop, until you play the multiply game again.
19  Economy / Gambling / Re: FreeBitco.in - Win free Bitcoins every hour! on: June 16, 2017, 07:31:39 AM

i believe there are 2 threshholds you need to surpass in order to increase the bonus.
if you pass the first, you get half the bonus (see )
then there is another one, if you pass that, you get the full bonus. no steps in between. I do not know, how much you have to wager / how many tickets you have to buy. Maybe someone could test this?


so my bonus just changed to the full bonus . I guess wetsuit is constantly changing the system, trying to find what's best.
20  Economy / Gambling / Re: FreeBitco.in - Win free Bitcoins every hour! on: June 16, 2017, 06:57:06 AM
I just noticed that freebitco.in does offer a way to increase your free BTC rewards by up to a higher amount if the user play their multiply BTC dice or buy the site lottery tickets, I do try to roll quite a number of rolls but I doesn't see my free BTC payout amount increasing, is there a certain amount we must wager before the rewards get increase in the free roll?

i believe there are 2 threshholds you need to surpass in order to increase the bonus.
