Short answer: probably yes.
I wouldn't recommend iPoker for 6max turbos under 10$ because of the 20% rake. Think long and hard about this.
100 buy-ins is confy, but it can happen to lose them all if you are only marginally profitable ( with 5% or lower ROI ). Go and sharkscope players of huge volumes on 6max turbos (10kgames+) and see their breakeven and losing stretches.
Assuming you put the rakeback back into your account and you play decent volume you should be fine, IF you beat the 20% rake.
150buy-ins is what i would feel really confortable with and at 200 i would be extremely confident that if i have even 1% roi I won't go broke, even if i don't put the rakeback back into the account.
