Ah, of course... forgive my stupidity.
Anyway, I'm puzzled by Stars' decision to set a 10% rake on BTC.
In my understanding, a gambling venue prices each of its offerings according to how well that game entices a customer to deposit: it can afford to charge a higher house advantage on a jackpot slot than on a non-JP one because a JP slot is more addictive.
In poker, pricing is slightly more complicated because recs lose money not only to the house but to the regs too, and it's the sum of the rake and the losses to regs that should be kept reasonably low in order to prevent the rec from losing the interest in the game.
So the act of charging more rake for BTC than for Spins means that Stars believes in either of the two things: 1) BTC retains rec customers better than Spins, 2) regs don't have such a big edge over recs in BTC as in Spins. I actually think that Stars believes in both, but both are questionable.
Especially at the $1 BTC, recs time out quite often and are sat out and so they lose a ton of blinds during their disconnections because the dealing is Zoom; and those losses aren't fully compensated by the fixed duration of the game - surely, those who sit out but manage to survive until the end, do win some cash, but those who get disconnected early in the tourney just get blinded out very quickly and get nothing.
Thus disconnected recs don't have as much chance to cash in BTC as they do in Blast, where the dealing is non-Snap and even much slower than in Stars' non-Zoom games. (This Tuesday, I found myself in a Blast tourney where both my remaining opponents got disconnected, but alas that happened when the timer was already low, so both survived into the all-in phase, and one of them ended up winning the tourney
).
