Which is more profitable?

[FreeRoulette]

Play the same color for both bets.

Bet A uses a martingale.
Bet B lets the bet ride.

Both start out with the same bet amount.

When the martingale fails 7 spins in a row, which bet system did the best, or are they equal?

[Lucky7Red]

Martingrail did better.

Not sure if I understood exactly the question.

Still, let'S see.  If one reinvested not all profits, but parts of it, such as Fionnacci, if 7 win in a row or 6 win + 1 loss:

Spin  bet   win  br  lose  br
1          1      1      2     -1     0
2          2      2      4     -2     0
3          3      3      7     -3     1
4          5      5     12    -5     2
5          8      8     20    -8     4
6         13   13    33   -13    7
7         21   21    54    -21  12
