Interesting they say that casino betting limits eliminate the strategy. I don't think that's true.
Let's say you have $100k on the table, which is the maximum allowed, and you lose. All you need to is play multiple tables with the doubled bet ($200k) split up across those tables. Once you've played all of those to conclusion (maybe even splitting again...) you will have effectively "won" the line of play that they tried to stop you when you hit the $100k limit.
You say you won $10k, but how much money did you have? You said at one point you had $60k on the table so let's assume you had just that - if you put the entire 60k on something which has 7:6 odds then the odds of you winning are high but exactly what you would expect given the winnings compared with the bet.
When you play with the martingale strategy your odds of winning aren't any better, you just think they are because you don't realise your entire pot of money is actually at stake.
If winning at casinos is your goal, you're going to need to look elsewhere.
