Everyone with its own playing strategy and I wouldn’t have to condemn your strategy because at some point, it might be working for you and as such, I don’t have to start disputing that.
But I have some few questions for you:,
What if you loss your capital for maybe 5 consecutive times in your row, will you still be able to continue that your strategy and will you still be willing to want to double your money,

In a situation where it seems the casino is favoriting you, and you get to make maybe a little more above your expectations without any much stress, will you be able to stop for the day or still want to try your luck?

Personally the moment I make some winnings and I feel ok with it, I always leave and stop playing at the moment.
