What is the best way to divide... let's say... 100$ in 100 tosses such that you always atleast have the amount you started with, win more or not. Is it mathematically possible for such a thing?

With finite amounts of money & tosses/games it can't be done because there will always be a chance that you lose all games. With an infinite of money one could theoretically always bet double the last amount of money and always win back any losses.

The best strategy is always to go all in at the first toss then cash out.

These are all wrong. It’s been mathematically proven that the Kelly Criterion is the optimal betting strategy. In a fair coin toss (50/50 odds with 1:1 payout) the optimal betting strategy is to not bet at all.

Does the strategy take into consideration that if I don't pay my 200$ rent I'll live on the street?

Yes. But you need to factor it into the risk/reward ratio.

Bet the minimum
If you lose, double your bet
If you lose that, double that bet etc.

Small chance of losing everything you have, high chance of ending up the minimum amount in profit

That's litreally the worst strategy. Using this you are guranteeing that you'll lose it all eventually

I simulated this strategy with fund = 1000, if you lose then double, if win the return the bet to 1. I expect to lose all money before the fund reached 2000 half of times. But I actually double the fund 70% of times. Pls explain
