freebitco.in - is it even worth it?

[Salmon1989]

I made a script for freebitco using OCR that was autorolling, but there is problem that when they change captcha, program can't solve them anymore.

Is your script able to switch through proxies in addition to solving the captcha?

As far as faucets go, this is absolutely the best site that I know of.  I haven't seen a better one, it isn't hard to make some coins for very little work either.

[Biitcoin]

It's completly a waste of time , they make thousands with those ads & Captcha's and give you small amounts , like .. so small
Any faucet would be a waste of time on my opinion , I would advice you to try selling Digital goods or making services (anything you are good at , Programming , Designing , whatever)

Yup it has the highest average payment among all those faucets, but it is still very low and you won't get a good amount of bitcoin from it without lots of active referrals.

That is somewhat true.  I have like 2 referrals but I still manage to roughly get .001-.002 a week(With multiplying too)  I don't think its terrible its definitely not great but I say I do alright

[HeroCat]

You can multiply BTC, but then your balance must be enough large ~ 1 BTC,and chance of win low. If your balance is lower than 1 BTC, you can loose. 

[dothebeats]

freebitco.in is worth it if you have a good referral working under you. However, if you're alone visiting the faucet, then there is a very little chance for you to get a high profit from visiting that site.

[Aggressor66]

Try the “multiply bitcoin” feature to multiply your profit – but don’t set it too high or get too carried away and lose it 

[Aemon]

I also want to say that you don't need more than 1 BTC to gamble on this site.  You can gamble with any amount, and having more in your bank does not mean you will win, as a matter of fact you are probably more likely to lose if you have a higher amount because you have more to spend.

Honestly, as a faucet, it's still the most noteworth one, even without referrals. I've gotten numerous of the higher paying ones...although I'm probably just lucky haha

They give away order-of-magnitude multiples of 0.2 cents with the lowest roll payout being 0.2 cents and the highest being $200. I've calculated the expected value of a roll at 2.7 cents. This assumes the top prize is exactly a 1 in 10000 chance which may not be the case.

The site is provably fair which is true to get the 8-digit hex, but then what they do with it, that's where the devil is in the details, which in this case is in Point 4 below. The rules used to say the integer was rounded "UP" to the nearest whole number and now and it says the integer rounded "OFF" to the nearest whole number so that is a huge difference. Here is the explanation of the rules from their site:

Code:

Two strings are created : 
1. STRING1 = "[NONCE]:[SERVER SEED]:[NONCE]" 
    STRING2 = "[NONCE]:[CLIENT SEED]:[NONCE]"
    For your last roll : 
    STRING1 = "76:XY5UiZdUVqxX:76" 
    STRING2 = "76:t8GqWftzShE2yotF:76"
2. Then HMAC-SHA512 is used to hash STRING1 with STRING2 giving us a 128 character hex string.
3. The first 8 characters of the hex string are taken and converted to a decimal.
4. This decimal is then divided by 429496.7295 and rounded off to the nearest whole number.
5. This whole number is used as your roll, with the maximum possible value being 10,000.

If you convert an 8-digit hex to a decimal you need to get "ffffffff" in order to convert to 4294967295, which divided by 429496.7295, is exactly 10,000. You have exactly an 16^8, or 1 in 42,94,967,296, chance of rolling this exact number. So the question becomes what does "round off" mean. If they mean rounding up any fraction then there is really a 1 in 10,000 chance of winning the top prize. If they actually round any fraction down then the top prize is an unwinnable canard, 22 times harder to win than the Powerball! Or maybe the site means its a true mathematical rounding, so if you roll a hex that converts to 9999.5000 or higher you win, and then at least you can win the top prize 1 in 20,000 times. But in any event it would be interesting to see how many people win what prize tier and see if it ties mathematically to the number of attempts.

Here is the expected value per roll based on the three different scenarios, given the site continues to maintains $200 for the top prize and divides each tier down by 10 with the same probability for winning each tier:

Round Up: 2.71 cents
Based on what "Round Off" means:
Round Down: 0.71 cents
Mathematical round: 1.71 cents

You can see how much the top tier affects the total EV.

If anyone has actually rolled a 10,000 that would essentially eliminate the "round down" theory so post if you have. Then it's a question of whether you can win 1 in 10k or 1 in 20k times. Accordingly, if anyone has rolled a 0000 then hat would eliminate the round up theory, and we'd be left with the mathematical rounding theory (albeit, discounting the fact someone may have beat the 1 in 42 billion odds for either of those exact hex rolls).

I would not advice you to use the multipy option and never try Martingale system, because you will loose. {They have built in options, to defeat the Martinegale method}

I just luv this faucet to bits, literally   -- I even advertize some banners for other sites through them, and I help funding this, with the faucet income I get. {So even my ad's are cheaper}

Hell-of-a-lot of stuff going on there.

Still hoping they will use my idea, with the charity.

I've been using it since January on and off when I remember.  It's one of my pinned sites on Firefox, so I usually hit it up 5 or 6 times a day.  I have pretty much nothing to show for it.  I get more by making a couple posts through the sig. campaign I'm on.  If you can manage to get referrals that continue to play on a regular basis, you might get something worth while.  All my referrals stopped playing after a few days/weeks.

I do tend to play it more when the price of bitcoin is down.  Definitely get a better payout.  So lately, I've played it a lot more. Still hoping for that 10,000 roll, but I don't think it is possible.

yes refs matter a lot

[Glob]

It's worth it if you have fun doing it

[Joca97]

to get as much as money on this site you need lots and lots and lots of refferals
to make at least a few bucks

[Bananana]

Faucets is a better time waster then watching TV and playing online games. At least you get something out of it.

[Redwan]

I still think this faucet is a good place to start, for everyone.

According to the following post by wetsuit (in case you don't know, he is the owner of freebitco.in), it seems to me the site has been working with "rounded off", and so the EV should be 1.71 cents.

I am sorry, it should be "rounded off" and not "rounded up". I shall correct this on the website. So any number below 0.5 will be rounded down to 0.

hmmm so that probability to get "10000" should be just 0.005%.

Yes, because that is what is feasible to pay out. You gotta remember though that there is no other faucet or free bitcoin websites (that I know of) which gives you the chance to even win that much and that too using a provably fair system.

Freebitco.in create a new server seed for each of your bets. But if you are worried that the site create server seeds in a specific way to make all martingale players lose, you can change your client seed every bet. But that won't change the negative EV nature of the game.
