Betting Strategy: Win Profits 90% of the Time

[xNICK1]

Looking for help to try an make a profitable strategy off the example.
payout= 1:1
Using 4 rounds the strategy wins 1 of 4 rounds 90% of the time, the other 10% it loses all 4 rounds
Rules: if any round is won that game is over, else keep betting till all 4 rounds over
The question is how to I change the betting method to turn positive results
Key= g=game, r=round, b=betting amount, pl=current running Profit/lose
Ex1: 10 games of 4 rounds
g1: r1: b=1, lost, pl=-1 | r2: b=2, lost, pl=-3 | r3: b=4, won, pl=1
g2: r1: b=1, lost, pl=0 | r2: b=2, won, pl=2
g3: r1: b=1, lost, pl=1 | r2: b=2, lost, pl=-1 | r3: b=4, lost, pl=-5 | r4: b=8, won, pl=3
g4: r1: b=1, lost, pl=2 | r2: b=2, lost, pl=0 | r3: b=4, won, pl=4
g5: r1: b=1, won, pl=5
g6: r1: b=1, won, pl=6
g7: r1: b=1, won, pl=7
g8: r1: b=1, won, pl=8
g9: r1: b=1, won, pl=9
g10: r1: b=1, lost, pl=8 | r2: b=2, lost, pl=6 | r3: b=4, lost, pl=2 | r4: b=8, lost, pl=-6
Ex1: results to a -6 profit/lose after winning 9 trades in a row before losing 1
Is it possible?

Challenge questions are posted as a test to other members where the OP knows the answer. It seems to me that you don't know it yet.

Are you saying you already know the answer? It doesn't look that way from the problem statement. If so, my apologies.

No sir, I do not know the answer. Which is why I posted the question. I was unaware I needed to know the answer for this forum. My apologies.
