I like Blackjack and I have a decent amount of experience with it on Stake. I consider Blackjack as one of those games that can actually help overcome the house edge in the long term as long as you use optimal strategy as pointed out here.

It looks like you are using Martingale strategy here which is way too risky since I have encountered pretty long loss streaks while playing Blackjack on many occasions on Stake and other sites.
I liked blackjack because apart from its lowest house edge among the provably fair games I learned it easily even when it was basic when I first tried to play it. But I know I still have some unknowns just like the reference you shared discussing other rules, basic and text strategy. It just seems hard to remember. Thanks to that, I didn't know there was such a thing I don't know those yet because I only do hit and stand. I do not use Split or Double. I also do not take insurance. I only use soft 17 like most dealers.https://wizardofodds.com/games/blackjack/strategy/4-decks/

You are right that the use of martingale is dangerous because I have failed several times to use it. But I can't do anything because this is my only strategy now that sometimes and even works more often.
