Give me a martingale formula for betting strategy. Initial bet is 5, payout is 4.5. but the bet is taxed at 2% an then bet on. So for example if the bet is 100, minus 2% tax, so 98 and the payout is 98*4.5 which is 441. So my profit would be 441 minus 100 which is 341. Give me a strategy so that I don't lose money for 25 rounds

To develop a Martingale betting strategy where you don't lose money for 25 rounds, let's take into account the 2% tax on each bet, the payout of 4.5 times the taxed amount, and the initial bet of $5. Here's how we can structure the strategy:

### Martingale Strategy Adjusted for 2% Tax

1. **Initial Bet**: Start with an initial bet $ B_0 = 5 $ dollars.

2. **Tax Adjustment**: Each bet amount is taxed at 2%. Therefore, if you bet $ B_n $ dollars in the nth round, the effective amount bet is $ B_n' = B_n \times (1 - 0.02) = 0.98 \times B_n $.

3. **Payout**: The payout for a win is $ 4.5 \times B_n' $.

4. **Profit Goal**: To cover your losses from previous rounds, the net profit must equal or exceed the cumulative losses from all previous rounds plus the initial bet. 

Given this, the Martingale strategy involves doubling your bet (accounting for tax) after each loss to recover all previous losses and make a profit equal to the initial bet.

### Formula for the nth Bet:

Let $ B_n $ be the bet amount for the nth round:

\[
B_n = \frac{(1.02) \cdot (B_0 + \text{cumulative losses from previous rounds})}{0.98 \times 4.5 - 1}
\]

### Steps to Calculate Each Bet:

1. **Start with the initial bet**: $ B_0 = 5 $.
2. **Calculate the effective bet amount**: $ B_0' = 0.98 \times 5 = 4.9 $.
3. **Determine the payout**: $ P_0 = 4.5 \times 4.9 = 22.05 $.
4. **Net profit for round 0**: $ \text{Profit}_0 = 22.05 - 5 = 17.05 $.

If you lose the first round:

5. **Cumulative loss**: For the first loss, it's just the initial bet $ 5 $.

6. **Next bet**: Using the formula:

\[
B_1 = \frac{1.02 \times (5 + \text{losses})}{0.98 \times 4.5 - 1} = \frac{1.02 \times 5}{0.98 \times 4.5 - 1}
\]

Calculate $ B_1 $, $ B_2 $, ..., up to $ B_{24} $.

### General Recurrence Relation:

For each round $ n $:

\[
B_n = \frac{1.02 \times (B_{n-1} + \text{cumulative losses})}{0.98 \times 4.5 - 1}
\]

### Implementing for 25 Rounds:

To ensure you don't lose money over 25 rounds, you need to keep doubling your bet as calculated above. This strategy guarantees that a win at any point will recover all previous losses and make a net profit equal to your initial bet.

However, this strategy assumes you have enough capital to continue betting even after many losses, which can escalate rapidly due to the doubling nature of Martingale.

### Important Considerations:
- **Capital Requirement**: The capital required grows exponentially with each round, especially with a 2% tax applied.
- **Risk**: Even with a 25-round buffer, this strategy is risky. If you lose all 25 rounds, the accumulated losses will be substantial.

Would you like to see a specific example or calculations for each round?

### Relative Questions:
1. How does the tax impact the Martingale strategy compared to a non-taxed scenario?
2. What is the total capital required to execute this strategy over 25 rounds?
3. How does the 4.5 payout ratio influence the strategy’s effectiveness?
4. What is the probability of losing all 25 rounds?
5. What alternatives exist to the Martingale strategy in similar betting scenarios?

### Tip:
The Martingale strategy works well in theory but requires a very high capital reserve to sustain losses, especially with added costs like taxes. Always be aware of the exponential growth of bets when using this strategy.
