I don't see things that way. I don't think it's a good idea to participate in a tournament with such a small bankroll if you aim for such goals. Because when you reach such wager amounts you are competing with people who have very large bankrolls usually, high rollers or almost. They can place big bets few hours or minutes before the end of the tournament and steal your spot without leaving any chance for you to get it back. So personnally I rarely try to win the top spots and I prefer having some fun by playing for smaller ones instead of feeling stressed.
It's just my personal experience
You may not think it's a good idea but I play with relatively small bankrolls, and get good wager amounts when I need to.
Sometimes it's not even about getting top spot, remember Casino Live Hero? Maybe you were not around but you needed IIRC to wager 50 mbtc per day for 100 days straight. It was never about claiming top spot. What's the fastest/easiest/stressless way to do that? Autobet 500 times on 0.1mbtc of course!
I don't compete with SUPER big whales obviously and on Livecasino or Sportsbet that means top 10 usually is not even in my target. But at other sites like Blackjack.fun or Freebitco I have won 1st place on wager, usually following this strategy. People think I'm a whale then they learn how small my bankroll is. But I'm patient, I can do 10k autorolls per day no problem, I don't stress. If you have $100 and want it to last 10k rolls at about 1% house edge, you need to set each "roll" at $1. That gets you wager sum of $10k.
It's zero stress to play autobet and just come back every 2/3 hours around that to restart autobet.
