card counting online live?

so yeah, i get the argument that you can “count” cards on these crypto live blackjack tables since they use multiple decks and shuffle at certain points, just like brick-and-mortar. makes sense in theory, right? you see the cards, track the shoe, look for the shuffle point. i’ve run some calcs and sure, the count drifts, especially on those streams where they actually finish a shoe before shuffling.

but here’s the part i’m not sold on. i’ve noticed some places do these weird mid-shoe shuffles or have unpredictable deck penetration. doesn’t that nuke the whole point of counting? curious if anyone’s actually had any consistent edge doing this, or is it a total mirage online?
