Why is it a dumb idea for me to go to a casino and play roulette ONLY until I double my money or break even?

So I don’t gamble, and don’t ever indend to make it a habit.

But a friend told me to play roulette, and I would have a ~47% chance of doubling my money and , as long as I had enough money to keep doubling my stake, would have a ~95% break even if I kept going until I won and never played again.

So say I had $200k in the bank and always put my money on red

Spin 1 : $5K

Spin 2: $10K

Spin 3: $20K

Spin 4: $40k

Spin 5: $80K

Spin 6: $160k

In this scenario, I’d have a ~47% chance of winning $5k, and just a 2% chance of losing $160k?

EDIT: Although just working this out, I think I would probably put the 160k into a 4% savings account if I had it, or start off way smaller amounts e.g. $500 to reduce my chane of losing money significantly lol.

You’re going to double 5k, 10k and even 20k once or twice and then you’re going to max out your money and not be able to double out after.
