profitable method

following on from my last post..
1. many think x-games are rigged
2. many people can get a system to work well for a day, week month.. producing 100%+ profits per day

What about halfing ones bank ($500 in games wallet and $500 in main) pre betting
aggresivly bet the system until it doubles overnight
Then remove the $500 profit and continue the next night?

assuming the betfait bots dont take you out more than 50% of days this should work?

They ain't rigged, just random, but as there is a house edge of around 3%, long term profitability is not possible.   A bit like betting on a roulette wheel.

yea, im leaning more to the random side.

anyone see why this wouldnt work tho?
- your system doubles it self in a 24hr peroid more than 50% of days .
- when the days bets double, remove 1/2 and start the next day with the base bank again

surely this would work?
if 100 days are tested and 80% are "doubled" days, the chances of the next 100 days being below 50% are very slim. and even if the 2nd hundred days strike rate was above 20% (extreamly rare) we would be in profit for the 200 day peroid???

or

@ 80% win rate
start bank $100
2 of every 10 lays are -$100 days
8 of every 10 days are +$100 days

after 100 days, new bank $7300 !
and this is not compounding

i could be missing something?
the only possible system faliure is if the amount of success days drops below 50%, so how many test days would give a safe probability?
