It's a mindset that most of the time lead the gambler to lose everything, thinking that the bigger the bankroll the better chance of winning but in reality without good control of your capital, the chance of losing everything is possible, betting strategy is more on how you handle all the emotions and how you practice all your game plan, executing your plans is very important and not to allow any emotions as it can take you to wrong decision making.
the mindset of using a large bankroll is of course that gamblers will also increase the number of bets which makes the bankroll run out quickly.
I mean when a gambler uses a small bankroll say $ 100 and uses a minimum bet of $ 0.1 it will definitely last longer on each bet to get a lucky chance.
but when a gambler uses a large bankroll, for example $ 5000 but with a bet amount of $ 100-$ 200 it will run out faster. because a big bankroll definitely has the mindset to win big with big bets too.
and as far as I know, the faster the bankroll runs out, the more difficult it is to manage our bankroll, the more difficult it will be to find opportunities for luck.
so a good strategy is actually a strategy that can manage our finances in gambling so that it doesn't quickly deplete our bankroll and of course we have to control all emotions to stick to the minimum bet that can be enjoyed by each of our betting strategies.
If we are still talking about the martingale strategy, even by preparing large capital and starting with even the smallest betting basis, it will never guarantee that it will continue to produce positive results because the casino also has a max bet, which will be a barrier for any gambler to continue using his money until he returns get the win.
So keep on controlling our bankroll properly and get rid of the thought that there will be a strategy that is sure to give regular wins without ever losing so that we can make our money continue to grow because that never exists in gambling.
