For 2)
I mean if you have $50
Will you prefer this setting
Start : 100
Increase : x100 on loss
Restart when lose 2 time in row
Total cost for each 2 streak loss : $0.10
Or
Start : 100
Increase : x100 on loss
Restart when lose 3 time in row
Total cost for each 3 streak loss : $10
Hope you get what i mean, its something like will you rather to lose
$0.10 x 100
OR
$10 x 1
I am not a native english speaker, so it might be confusing, sorry for that ;/
Well then the second one is slightly better I'd say but there is no real difference.
What you propose is basically a Martingale with small odds.
The only difference with a classical Martingale is that you won't lose often and you'll win only extremely small profits when you win...
