Gambling is based on luck and there is no guarantee that you will win even at the beginning.

Higher balance and a low initial bet amount causes you to have to repeat the martingale method more times. However that causes the number of consecutive lose before failing decreases, it causes you to have a lower chance of winning.

How much money do you think is needed? Are 21 millions bitcoins enough?
As you yourself said you will eventually lose all. But note that it will finally happen even of you have all 21 millions bitcoins.

Yes, you can manage your money to not gamble more than you can afford. This only decreases the amount you less if you can overcome greed. But money management cannot overcome the house. The house give your money. Does not matter it's a big money or only a few cents.

For bumping a topic you should 1. make a post on that or 2. click on the "bump" button ( If you have merits)

1. make a post (mini bump)
It is not allowed to ask bounty hunters to make a post on a certain thread because:

2. Click on "bump" button (super bump)
It's impossible to track who has clicked on "bump" button. Also, bounty managers have not access to the amount of bump power of bounty participants.

Winning is never guaranteed. You might lose all your fund only in few seconds. Charts show that the time of losing is different, You might lose your first 10 or 20 bets streakly. Every thing is possible.

What do you mean starting again? Using Martingale strategy, we are actually starting again several times.

No. I used my own codes.

The house doesn't allow you to win even you use different odds. You can only delay the losing time.

For this, you need to have a big initial amount of bet. That cause you to lose even sooner.

Yes, you are right. But bigger amounts only delay your losing time.

Exactly, We don't know when the pocket will become empty, but it will finally happen and as charts show, that usually happen very soon.

Yes, The method is not profitable. I made the diagrams to show that to any one likes this strategy.

No difference which cryptocurrency is.
For example when the bet amount is 1 and the initial balance is 1000, we can say bet amount is 1 satoshi and initial balance is 1000 satoshi or bet amount is 1mbtc and initial balance is 1 bitcoin.
This can apply to dogecoin, litecoin, etc. What matters is the rate of bet amount and initial balance.

They can be obtained too. It's a bit time consuming. I had calculated the probability of winning theoretically when the initial balance is 1 bitcoin and your initial bet amount is only 1 Satoshi.

I repeated the simulations many times to prove what you are saying better and more visible. And I didn't claim that we can beat the house. I proved the opposite.

No, to prove that it's not profitable.

Here I would like to share my simulations to test Martingale strategy.
The house edge is 1% and bet multiplier in loss case is 2.
The calculations continue until the bet amount is lower than balance.
Hope it is helpful for any one interested in these strategy.
Give your opinions about the results obtained.

LoyceV made a graph to show the change of super power over time when someone uses the super bump once per day. According to this graph, if someone super bumps topics once per day, the super bump power will finally stabilize to 18.69
So, the effect of the person who super bumps one topic per day only by a simple click is about 19 times a person who makes a post on a topic. I think this effect is very big and is not reasonable.

After I saw LoyceV's graph, I decided to make some other graphs to show the effect of super bump power with different number of bumps per months and also show how super bump power will finalize with different number of bump the person done.
I assumed that the bumps are done regularly and the base bump power is 100 (like LoyceV)
Therefore,
1 super bump per 30 days = 1 bump on day 1, next bump on day 31, ............
2 super bumps per 30 days = 1 bump on day 1, next bump on day 16, ..........
10 super bumps per 30 days= 1 bump on day 1, next on day 4,............

If someone super bumps topics 5 times per 30 days



If someone super bumps topics 15 times per 30 days



If someone super bumps topic 30 times per 30 days (It has been already made by LoyceV)



If someone super bump topics 90 times per 30 day (3 times per day)



The diagram below shows how the super power will stabilize with different number of bumps made per 30 days.


According the results obtained even if someone uses the super bump power 6 times per day, the effect of his/her bump is still 3.6 times the person makes a post on that topic. Also consider that the super bumper is able to bump the topic every 24 hours.
In my opinion, the effect of super bump should be decreased.

Here are the rates of super bump power to base bump power for different number of bumps per 30 day.
1 bump per 30 day: 100%
2 bumps per 30 day: 86.96%
3 bumps per 30 day: 76.92%
4 bumps per 30 day: 68.97%
5 bumps per 30 day: 62.50%
6 bumps per 30 day: 57.14%
7 bumps per 30 day: 52.63%
8 bumps per 30 day: 48.78%
9 bumps per 30 day: 45.45%
10 bumps per 30 day: 42.55%
.
15 bumps per 30 day: 32.26%
.
30 bumps per 30 day: 18.69%
.
60 bumps per 30 day: 10.00%
.
90 bumps per 30 day: 6.90%
.
120 bumps per 30 day: 5.26%
.
150 bumps per 30 day: 4.30%
.
180 bumps per 30 day: 3.57%  

A mini-bump (bumping by making a post): 1%

I thought he means the bonus that we can claim in "Multiply BTC" section. Maybe I am wrong. If he means the Lambo Tickets, you are right. There is no need to wager for that. Every one has the chance to get 1 free Lambo ticket for every 0.05 BTC deposit without any withdraw limit.

Really? It's the first time I've heard about this. Is there any link to an announcement or any other thing help me for more details?

Do you now that you need to wager 25 times the amount you claim for bonus before you become able to withdraw that?
I guess you live in a country with a very low inflation rate and good economic condition. Never be sad for low interest rates. Do you prefer to get 30% interest rate but have 50% inflation rate?
Any way, I agree that the interest rate on freebitco is really fair and fine. Freebitco has many other good options such as easy sending and receiving bitcoin, the weekly lottery and now its Lambo lottery. You can also bet on different events and enjoy it.

From my understanding Modified bump power is calculated and is only used for super bumps. If the points users give to topics by mini bumps was supposed to deducted from the base bump power, It would be mentioned by Theymos as it is clearly mentioned for modified bump power which is affected by super bumps.

So,
1. Mini bump power only depends on base bump power. If you mini bump 100 topics, all of those 100 topics will be affected by a same point as long as number of your merits doesn't change.
2. Super bump power depends on base bump power and number of your previous super bumps. (That's why modified bump power has been introduced)

Some one has bumped it . There are two kinds of bumps. 1. Mini bump 2. Super bump
For mini bump you must make posts.
For super bump you only need to click on "Bump" button.
A high-merit user has likely clicked on the button. ( Maybe more than 1 user)
As the bump power decreases by time and becomes zero after 36 hours, such topics cannot remain on the top.
Some one has misused the bumping points or some one has tested it.

Almost all of those shit posts on tokens threads are made by users that have not earned any merit in the last year and their bump power is exactly zero.
But generally you are right. Any one spams should be reported. No difference it affects bumping or not.

I just sorted the topics on Announcements (Altcoins) by the last post. 21 posts that were on the first page when sorted by bump score remained on the first page after new sorting. It's 64% of the topics on the first page. (The total number of topics that are shown in the first page is 33). This percentage should increase over time. Gradually, number of the spam posts that used to make on some topics decreases and posts shown when sorted by bump score and the last post becomes more similar with each other as spammers leave the board.

I just checked the last page of some topics that are on the top of Announcements (Altcoins) board. Except a few ones, all of them include posts by high-merit users. Now at the time of writing a random topic which has posted in 2014 and has not received any reply is on the second place. I think one of high-merit users has bumped that only for testing. (It's great that it is affected only in 36 hours)
It's great that I can see the threads that are of interest to high-merit users.

two suggestions:
-Now the effect of clicking on the "bump" button is 15 times the effect of making a post on a thread. As a user can give bump score to a thread once per 24 hours by clicking on "bump" button and once per 7 days by making a post, the effect of clicking on the "bump" is much more.
I suggest to decrease the effect of super bumps.
-A bad review shouldn't help a thread bump. So, users should be allowed to make posts on threads without giving them bump score.

Edit: Now it's really difficult for new topics to be on the top. I think the effect of topic starter can be considered more. In this case, If a thread is started by a high-merit user, it has a more chance to be on top at least for 36 hours.

I also don't know how the amount of bonus that users are eligible for is calculated. I tried to find something in the website, But I couldn't.
Due to the 5% house edge, the website will never lose even if they allow users to claim bonus as much as they have bitcoin on their balance. Maybe they want to encourage players to wager more before claiming bonus.

Completely right.
Here I give an example to make it more clear.
I claim 1000 Satoshis. 1000 Satoshis will be deducted from my balance and I will have 2000 Satoshis on my bonus account.
If I play HI/LO game and I wager 1 Satoshi 1000 times, the house edge guarantee that I will lose 50 Satoshis. (In long term, it is 100% true and that's why I considered the amount of each bet only 1 Sathoshi).
To become eligible to withdraw my balance from my bonus account, I have to wager 1000*25= 25,000 Satoshi. So, I will lose 1250 Satoshis. So, I become eligible to send the entire balance from my bonus account to main account when I have only 750 Satoshis.

Many of the bounty hunters select the bounties based on the percentage of the tokens that are allocated to bounty and ICO price.
For example, a token total supply is 1,000,000,000. Each token cost 0.05 dollars ( what is written on bounty thread), 5% of the tokens will be allocated to bounty hunters. 25% to signature campaign.
The bounty hunter makes a simple calculation.
1,000,000,000*0.05*0.05*0.25=625,000 dollar.
The bounty hunter thinks that 625,000 dollar will be allocated to signature campaign participants. Then the bounty assume that he/she can earn at least 1% if the tokens that are allocated to signature campaign. So, the bounty hunter can earn 6250 dollar only by making 10-15 posts weekly for 8 weeks (as an example).
Many of bounty hunters think this way and this is their own fault. Earning money is not this easy especially in a market which people are no longer interested in ICOs/IEOs.

First, that number of tokens are usually allocated to bounty hunters only if the token sale reaches its hard cap.
Second, the real price is always lower than that price. You should consider the bonuses and especially the big discounts that are given to big investors privately.
Third, there is no interest in investing in ICOs. When there is no interest in ICOs there wouldn't be interest in buying the tokens on the market and the trading price will be lower.
 
It's your own fault if you think you can become rich only by making some posts in the forum.
If it was possible to big that big amounts of money in bounties, be sure trusted member of the forum were participating in these bounty campaigns instead of some bitcoin signature campaign with very lower profits.  

I think if a project is trustworthy enough and has something to be attractive for investors, there is no need for any bonus or discount to attract investors. Giving bonus is the easiest thing a team can do.
Sometimes bonuses cause the people to not invest in the project. Assume that some people have given 40% bonus at early stages. Now people afraid they dump their tokens. So they decide to not invest in the project. For solving this problem, they give 40% bonuses in next rounds too which means deceiving early stage investors.
So, I think 40% bonus is really big. In my opinion, bonuses shouldn't be higher than 10%.
The biggest problem which is the main reason of price dump in most of the projects, is not these bonuses. Usually, there are very bigger bonuses that are offered to big investors privately. When a token price dump 90% immediately after listing on exchanges, be sure there are some private investors that are making profit even by selling at 90% under ICO price.
Generally, 40% bonus is big. But I appreciate a team which give early investors 40% or even 60% bonus but they don't give higher bonuses to some others privately.  

What I see under the "Off-topic" on the home page is: "Other topics that might be of interest to bitcoiners". According to this I don't think posts made in "Off-topic" board can be completely unrelated to cryptocurrencies.
I don't think topics about asking the favorite food, the favorite game or the favorite movie should be discussed on bitcointalk even on "Off-topic".
I don't think bitcointalk is an appropriate website for discussing whether should have a child or not, how to sleep better or how to spend free time.
Checking some signatures and their bounty threads, I found out there are some signature campaigns (including a few bitcoin campaigns) that are paying to users even for making posts on "off-topic" board.

I guess the OP has withdrawn some amounts of Bitcoin and expected that amount to be sent from the deposit address and that's why it is said that "the address in not mine".
If I've understood the OP correctly, the answer is simple.
The wallet which the OP is using is a wallet which user has not full control over the bitcoins. It might be an exchange.
You deposit some bitcoins to the wallet, then that amount of bitcoin is sent to another address which is likely a cold wallet. When you withdraw some coins, they are sent from another address as your deposit address is empty.

There are always some topics created by newbie alt accounts complaining about banning of the main account. If you read the posts, you will find out the reason of almost all of them is plagiarism.
Whenever I read the replies and find the post that has been copied, I say " How smart is the reporter"
As there are many posts in the forum, I think finding copy-paste posts is really difficult.

Please any one who has experience in finding copy-paste posts tell us how did you find them?
Any idea how can we find plagiarism?
Any one knows a strategy? If yes, let others know that. It can be helpful to find all copy-paste posts.
