You need bigger bankroll for this to matematically to be in good spot.
Only play then their blackjack with 0.28% house edge, nothing else.
I agree, it's all mathematics (probability, likelihood of losing as little as possible while making 1 mbtc wager 100 mbtc haha) and the lower the house edge, the better. So Blackjack is the only thing to play long term.
However, to avoid variance, play smallest amounts, but you'll get such a slow wagering effect (this is the reason I asked for auto).
In this case roulette can help you a lot (but high house edge).
on french roulette but I only do this 1 time because I'm affraid that it might cause me a lot if continue hitting 0 too early before I even farm enough wager. I agree that automatic blackjack is our best to farm wager with low house edge and probably not burning huge money before we get enough wager volume to hit target.
