I have experienced both not only online but in brick and mortar casinos as well.

One thing about perception and online play is that, while the frequency of rare events remains the same, it feels like these things happen more often online because, in terms of elapsed time, they do. On some online (but not live) blackjack apps, I can play between 600 and 700 rounds per hour. It's like experiencing an hour of fast real-life play every 10 minutes or an hour of slow play every 6 minutes. You will see a lot of "rare" stuff happening during a 2 or 3 hour online session. If you play online regularly you'll see a decade's worth of "rare" occurrences every year.

The probability for a 20-streak in 700 rounds is extremely low. Even in 7000 hands (10 hours). Worse, only the negative streak hits the player. How many 20-hands win streaks did you have in any, say 7000 rounds? Zero, reality or perception. The long streaks are lobsided in favor of the house. It is not “the memory is selective” as casinos explain. No offence, just my honest exposure.

It is. However the problem is that you aren't measuring the probability of a losing streak you are measuring the probability of a losing streak in a dishonest game.

Even with quite a lot of cheating the probability of experiencing such a streak is quite low.

It really is better to focus on a large sample size rather than something weird which happened within it.

This might as well be advertising in disguise for online casinos

To make this clear: I fucking hate the gambling industry. Online is every bit as bad as offline.

That said I made a ton of money online, mainly from bonuses. Cheating is no worse than offline: I have a huge sample of play to justify that.

Card counting offline and online is a very weak form of advantage play with extreme fluctuations. Most people who try it will give up. I don't recommend it to anybody.

I agree. I didn't say I was seeing this kind of streak once every 700 or 7000 rounds. I said that I have seen them during my career, both online and in real casinos. These are once in a lifetime events in a real casino but possibly several times in a lifetime playing fast online apps.

Worse, only the negative streak hits the player.

Not in my experience. I have seen them both ways.

How many 20-hands win streaks did you have in any, say 7000 rounds? Zero, reality or perception

This question has no meaning. I have seen such a streak, meaning it is not impossible. During which particular 7000 rounds it happened is irrelevant.
