Simulating whether there was a gain at some point

What is checked is whether there was a point where the balance was greater than the initial balance.

for bet_amount in range(10, 110, 10):
    gain, loss = 0, 0
    for money_history in money_histories[bet_amount]:
        if gain_at_some_point(money_history):
            gain += 1
        else:
            loss += 1
        
    plt.bar(['gain', 'loss'], [gain, loss])
    plt.title(f'Bet_amount: {bet_amount}')
    plt.show()

Simulating how many bets are needed for bankruptcy, depending on the percentage of the initial balance that is bet

for bet_amount in range(30, 110, 10):
    plot_number_of_bets(money_histories[bet_amount], f'Number of bets for bet_amount: {bet_amount}')
