An individual game is more based on skill of course, as anything can happen in short stack poker. However of course over the long term your skill can prevail and you could win some money.
Here is the problem tho, the rake!! Lets say you play 100 games, a really high win percentage is probably around 40%, this is very good. But the rake on GG is 7%, I would imagine it is similar on stars. So the reality is that even if you are winning a decent percentage of the time, the rake is likely to send you back to a roughly break even point. Plus, remember you also have to be very good to get this win rate in the first place!!!
Don't worry so much about needing a high BR, maybe $50 for 0.25 spins if you are a roughly break even player, spins are not nearly as high variance as MTTs as there are only 3 players....so if you are equal skill as the other players, you will win 1 out of 3!
Try playing 100 games and track your results, then come back here with what you have achieved. This is the way to start.
I don't think it is realistic to win $20-$50, unless you are very good, get lucky with big multipliers, or can move up to higher stakes and still maintain a good winrate!
In terms of the best strategy, I think its best to play very tight and very aggressive, wait for opportunities, and understand that if you are not picking up cards, but you can survive until the blinds have gone up then things can change very quickly, so its worth trying to cling on, and not just shoving your last few chips with garbage!
This looks like a very interesting article on spins strategy!
