I doubt that high rollers enjoy Martingale using it while gambling. Of course, if a user has a few bitcoins, then using such a strategy as Martingale might allow him to avoid losing the entire deposit due to a long losing streak. However, it also means that every time a user should start gambling with a minimum bet of literally 1 sat because even 25-30 losses in a row will be an unpleasant experience for a high roller.
Can a high roller enjoy gambling with an initial bet of 1 sat? I don't think so.
If you start with 1 satoshis, you can have some losses but I think the high rollers start at some higher numbers maybe even a few bitcoin in one bet lol.
I think there is still a lot of ignorance about the Martingale strategy; I have a buddy that I went to the casino with recently (in real life) and he kept talking about that with Martingale you couldn't loose and that is not possible to have 20-25 losses in a row.
