Martingale makes it easier to win a small amount, but it also makes it easier to lose a big amount than a flat betting strategy, and that is where the problem lies.

Here is a math problem to find out why martingale isn't the best idea. Whatever game you are playing, what are the odds of winning 10 games in a row, and what are the odds of losing 10 games in a row? Very close, if not the same. How much do you win when you win 10 in a row and how much do you lose when you lose 10 in a row? Big difference, and the problem.

The reality is that it's just not worth it in the long run, that big losing streak will come, and it will wipe out of all of your previous winnings and then some.
please read the OP. I'm comparing an all in method with a martingale one, with the same goal (eg 8 btc from 7) and then the all in method is worse than the martingale...

A major difference between OP's strategy and normal martingale players' strategy is that OP will only do 1 round of bets. When he wants to make 1 btc profit, he simply set his base bet to 1 btc and stop right after achieving his goal.
This way he effectively lower his wagered amount from 7 btc to about 3 btc (50%*1btc+25%*3btc+25%*7btc) and as a result has a higher probability of making 1 btc than the all-in strategy.

But if he set his base bet to, say 0.0001 btc, he will need to make 10000 rounds of bets to make the 1 btc, which will have a very high wagered amount and much lower success probability than the all-in strategy.
no, the total average amount wagered would be exactly the same. Trying to earn 1 btc in 1 martingale bet loses on average x, trying to earn 0.0001 btc loses on average 0.0001*x, trying this for 10.000 times (to have 1 btc profit) will give an average loss of 1*x too. 1 martingale or 10000 small martingales, it's all the same. Average wagered amount will be the same too taking into mind that the average loss is a % of the total amount wagered. Please think before you say something

Let's say you set the base bet to 0.0001 btc.
For each round of martingale, you will wager 0.0001 for 50% chance, 0.0003 for 25% chance, 0.0007 for 12.5% chance, ... , 3.2767 for 0.00305% chance, 6.5535 for 0.00305% chance, right?
So you will on average wager 0.0016 btc per round, and a total of 16 btc assuming you didn't hit a 16-loss streak, right?

Exactly. The OP can't do math, yet keeps telling others they're wrong. eh.
702  Economy / Speculation / Re: 2016 Halving: Could It Actually Kill BTC? on: April 11, 2015, 02:10:28 AM
I agree with the OP. I don't know why so many people automatically assume that halving mining rewards would double the price.

Personally I think this is where bitcoin will prove whether it'll succeed or fail. If it doesn't get past the halving, it'll fail. If it does, I think it's very unlikely for bitcoin to fail afterwards. And I'd certainly be willing to take any amount of loan to buy as much bitcoins as possible then, if someone offered to loan me money.
703  Economy / Gambling / Re: Martingale isn't that bad on: April 10, 2015, 09:50:15 AM
felt bored and calculated it
so imagine you have 7 btc and want to make it 8 btc and there is a house edge of 2%
chance you'll be able to do this with martingale is 86.375%
chance you'll be able to do this with a bet of 7 btc is 85.75%
just a difference for exactly the same outcome


Your calculations are wrong, with a 0% house edge doing it with martingale is a 87.5% and doing it all in with 7 btc would be also 87.5% so it doesnt matter wheter you use martingale or all in, the only thing you win is time
This is also false. The distributions are not the same, even though the end effect is the same.

Consider one family with a 1.80m tall father, 1.60m tall mother, and a 1.70m tall son. The "expected height" of the family is 1.70m.

Consider another family with a 2.00m tall father, a 1.60m tall mother, and a 1.50m tall child. The Expected height is also 1.70m, but obviously the distribution is different.


It's the same thing with gambling strategies. The EV is the same, but distribution is different. In the case that you want to win 1BTC and EXACTLY 1BTC, no more, no less, with EXACTLY a 7BTC bankroll*, there are two optimal routes**:

1. Bet all-in at high odds
2. Martingale with a BASE BET of 1BTC.

These result in the same odds for earning exactly 1 BTC. Any other variation of the martingale would result in a lower chance.

*Any difference in ANY of the variables would change this conclusion.

**There are possibly other routes that would arrive at the same % chance, but these are not within the topic of martingale vs all-in.
704  Economy / Gambling / Re: Martingale isn't that bad on: April 10, 2015, 07:19:41 AM
Don't misunderstand me, martingale is a losing strategy, just like every strategy, the house wins in the long run due to the edge.
but it's a better (or less worse) strategy than going all in, that's all i said
I'm not misunderstanding you, you're misunderstanding me. Your calculations are wrong, because martingale doesn't give the same probabilities for different starting amounts.

i think he/she just mean that with 7BTC, if you want to make it to 8BTC it would be better to make a martingale until you reach 1BTC profit instead of yolo bet
You're still not understanding me. I don't know why you guys don't understand such a simple point.

Martingale with 0.1BTC as the minimum bet does NOT YIELD THE SAME RESULT as martingale with 0.2BTC as the minimum bet. So to say that "martingale has an X% chance" is wrong.

Martingale works great until it doesn't.  I agree with waterpile that the key is to set your win target and stick to it.  That seems to be what trips up most gamblers.

I like the idea of comparing it with one all in bet.  It seems that dooglus did something along these lines awhile back.  IIRC he found that you were actually better off betting smaller amounts at high odds rather than one all in bet.  This makes sense if you think about it, your expected value is the same but your amount at risk is lower.  But I'm not sure if that extends all the way to martingale.  Your calculations suggest it might.

Regardless, good luck!
Either you're confused yourself, or you just didn't express yourself properly.

Expected value factors in risk. Expected value includes everything. You aren't better off under any strategy, they're all the same.

What changes is the distribution of possible outcomes. With bets of smaller amounts, you have a higher chance of losing smaller amounts, but also a higher chance of winning lower amounts. With larger bets, you have a higher chance of losing larger amounts but also a higher chance of winning larger amounts.

That's all. There's no "better". It just depends on the individual's definition of "better".
705  Economy / Micro Earnings / Re: how much can you make weekly? on: April 10, 2015, 07:06:39 AM
Actually, if you were really to truly work on faucets every single day non-stop for a week, say 8 hours a day, you can make quite a bit. Not as much as a job, but it's probably more than you'd think.

I would guess that you could make about $1-1.5 per hour with faucets. So 56 - 84 per week, ~0.23 - 0.35BTC/week.

This involves NOT wasting ANY time at all, so you can't lose focus, go to the washroom, drink a cup of whatever, etc.

Your calculations are wrong. How did you calculate this?

The thing is, with different martingale systems, the result is different. For example, is your starting bet 1BTC? Or 0.1BTC? Or 0.01BTC? Or 0.5 BTC?

The probability of obtaining a 1BTC win (and only 1 BTC) is different in each of those scenarios.

Wow, it looks like we're going to the moon!!!

709  Bitcoin / Bitcoin Discussion / Re: Bitcoin is just to complicated for the average person to use.. on: April 09, 2015, 11:19:31 AM
You guys need to stop being bitcoin cultists and look at this objectively. Using bitcoin gives 0 benefit over fiat to the vast majority of people. Instead, they'd have to pay fees to exchange it, and to transfer the bitcoins to their own wallet, then again when they're using it. If I withdraw cash through interac, I don't pay anything. I don't pay anything extra when I'm paying the merchant either. With credit card, I can pay on credit. It's also extremely easy to use.

Why would I spend the effort to obtain bitcoins? The answer is that there is no reason, unless you're a libertarian bitcoin cultist. Seriously. Stop saying "You can obtain bitcoins by doing this, this, this, this, this, this and this". I can obtain fiat without doing all those steps. I get no benefit from doing those steps. Why should I do it?

Again, whether something is complicated or not depends on what that thing is/does. spending 1000 hours working to become an olympic champion is easy. Spending 1000 hours working to buy an Aero bar is extremely stupid.

710  Bitcoin / Bitcoin Discussion / Re: Bitcoin is just to complicated for the average person to use.. on: April 09, 2015, 08:08:01 AM
Bitcoin certainly isn't that complicated to use, but it's quite complicated to obtain/buy.

Definitely not. Go to Localbitcoins, and there are multiple options, such as Skrill, Western Union, SWIFT Transfer, M-Pesa.etc to purchase / sell Bitcoins. It is really easy.
Uh, no it isn't? I'm a Canadian citizen, but I'm in China right now. I can buy food, or clothes or a laptop or a tv or even a house. But I can't buy bitcoins, because I need all sorts of proofs, phone authentication, etc. I don't have any of the services you mentioned above (except swift through the bank), so I'd have to register for those and then register on local bitcoins, and then find someone who is trustworthy enough, and somehow make them trust me. And even then, the closest people on localbitcoins to where I am now is an hour away. And I'm in one of the largest cities in China. That's not "really easy", lol.

For a normal person, if I can just get cash through an atm or pay with a credit card, why would I bother spending so much time and effort and fees to get bitcoin?

There are hundreds of sellers with good reputation in China. Many of them accept Western Union. Is it that hard to go to the local branch of Western Union, and make the payment?

You clearly are not getting the point. Are you willing to drive 3 hours, give out all your personal information, wait for confirmation, just so you can buy a more expensive and shady knock-off of an Aero bar?

Is it "that hard"? It obviously depends on what you're trying to do. For that amount of effort, if I could cure cancer, cure old age, and earn a billion dollars, yeah, it's not hard. For a freaking bitcoin? Of course it's complicated!

the difference between the internet and bitcoin is nobody ever stole 3/4 of a million internets ...

That's right, Bitcoin is not very hard to use, any internet user can figure it out in minutes but keeping the funds secure might be little difficult for some people as hackers are finding newer ways of breaching in computers.
But people have lot a lot of money through internet scams. If you think about it, bitcoin scams are a part of internet scams as well.
713  Bitcoin / Bitcoin Discussion / Re: Bitcoin is just to complicated for the average person to use.. on: April 09, 2015, 03:43:39 AM
The main downside to bitcoin is all of the hacks and scamming. It gives bitcoin a bad name. But then again hacking/scamming is unavoidable as credit card details are often stolen as well. Security will always be an issue as long as people are greedy and feel the need to steal from others.
It's quite sad, seeing as the people with the technical know-how of how to hack these systems and remain anonymous would probably be able to start very profitable legitimate business that benefit the world.

716  Bitcoin / Bitcoin Discussion / Success rate for Game Changing Technology/Food for thought on: April 09, 2015, 02:07:19 AM
We always compare bitcoin with the early personal computer, or the early internet, or the early automobile or electricity. We say how there were many people who were against these inventions, but they ended up changing the world. These were the success stories.


How many such potentially world-changing technology did not make it past that stage? Is the success rate really 100% or close to it? On one hand, that seems to be possible, given the world-changing nature of it. But if a potentially world-changing technology didn't get past a certain stage, most of us would have never heard of it anyway, so we don't know that it failed.

It's kind of like how we only hear of the successful entrepreneurs like Zuckerberg or Bill Gates, but in reality many more fail.

This question brings two discussions.

1. If the success rate of world-changing technology is actually not that high, can we really be confident that bitcoin will pull through? Of course we're under the assumption here that bitcoin really is a world-changing technology.

2. Are we, as humans, potentially hundreds of years behind where we could've been, had all the potentially world-changing technology became mainstream? Maybe we'd be all living lives we can only dream of now. Think of how many great opportunities you missed in your life, and how that would've changed your life. Perhaps those missed opportunities are completely insignificant compared to the missed opportunities of man-kind. And it's not like how we don't yet have the technology to create a perfect AI, or cure aging. Rather these are opportunities that could've happened. Someone really developed it, but we, as humans, simply failed to see the benefits and threw it away.

You do realize that we're in a phase of finding the true bottom and are struggling to achieve a breakout off the 15-month bear market(!!!) If the turnaround has been confirmed, we will go up. Big time.

The bottom is in at 152$, trust me. At least 2 people have confirmed it as this number appeared in their dreams prior to the actual manifestation of the bottom itself.
Oh my god thank you so much! I have never seen such concrete and unarguable proofs in my life! This is without a doubt the truth.

720  Bitcoin / Bitcoin Discussion / Re: Anyone realize about this? three BIG banks in three different continents are ... on: April 07, 2015, 12:42:07 PM
Banks probably have a worse reputation right now than at any other point in history.  People only put up with them because they don't think there's an alternative.  They don't need to "wake up and realise" anything, they just need to see something that works and provides a practical benefit and that's what we're working towards.

Also most people don't give a crap about anything important, which is why everything is celebrity gossip and reality tv these days.  That doesn't mean we should stop doing what we're doing and it doesn't mean we aren't going to see a surge in use in the future.

Your post also assumes the global economy getting better, but not all of us see that happening.  Since banks now have their dirty little fingers in so many pies, all it takes is for a few markets to take a downturn and they're suddenly in deep financial trouble.  If more bail-ins like Cyprus happen, you can bet people won't be prepared to tolerate that and will be looking for a way out.
Even if banks have a worse reputation right now than any other point in history, banks in general still has a better reputation than bitcoin. The current bitcoin doesn't provide a practical benefit for the majority of the people.


people don't give a crap about centralization either, you are really naive if you think otherwise, they just use banks to store money because they are accustomed to it there is no other reasons, the humanity is lazy animal, they want everything ready, don't like big change and other lazy things like that.

bitcoin success isn't a thing that a man can achieve, it need time/adoption and the fix of numerous weaknesses(like 51%, various unknown bugs in the client, ecc...)
No, they don't give about centralization. I never said they did. You're falling into the logical fallacy of assuming the converse is always true.

Your point that humans are lazy is exactly the point I was trying to make.
I don't think bitcoins are 'delusional to "decentralized" hype'. Sure it is a benefit to most here but that's not the only selling point. I think you have to admit it really has the potential at least to shake up the current banking system or payment processors. There's also a multitude of uses for it as an alternative currency and remittance tool.

I also agree that it's not the only selling point. In fact, I would say it is the biggest disadvantage and obstacle in an otherwise great technology.

Look, I think you guys are misunderstanding my point. I'm not saying bitcoin will fail. I'm saying if people keep thinking that bitcoin will succeed without anyone doing anything because decentralization is so freaking amazing, they're being delusional. For bitcoin to succeed, there needs to be thousands or tens of thousands of people working hard to make it more usable, more secure, and bring benefit to the average person. It won't succeed just because it's decentralized, and there is a long and tough road ahead. It's not hard for banks/governments to make the media write negatively about decentralization and telling people they need banks and the government, and given how stupid/lazy normal people sheep are, they'll just believe it without researching anything themselves.

It's a really tough road, and we should be doing all we can to get it going, to make it go mainstream, if we really believe in this technology. Because it's not going to that by itself.
