It's important to remember when playing satellites that it's actually not really that different to buying into the tournament itself, if the site you're playing on offers the chance to take 'tournament $' in the same way that PokerStars does.

Hypothetically if you play a lot of MTTs, then $100 of real money in your bankroll is virtually the same as T$100, so paying that $100 to enter the target tournament actually means you're spending $100 of potential buyins to other tournaments, just like you would be if you bought in for real money.

Treat satellites just like any other tournament. If they're soft and you have a big edge in the games, play lots of them, and take the T$ if you can. If they're not so soft, or if you can't take the T$, a different approach might be necessary.

Overall, one thing I'd recommend considering when it comes to bankroll management is the average field size you're playing in. That factor is going to have a huge impact on the level of variance you're subjected to, so I've heard people throw around ideas like “your bankroll should be your average field size multiplied by 50” – that's a little arbitrary, but it's useful.

I'd imagine a conservative approach will serve you well in your early days as an MTT player, so try to strike a balance between playing buyins that keep you interested, soft tournaments where your ROI is high, and small fields where you're not subject to huge variance. You can play satellites and take shots at the target tournaments from time to time, but stay disciplined. Everything in moderation. There are no hard and fast rules, but erring on the side of caution is rarely a mistake in this case.
