Speaking of budget and planning your bets, the recommendation is that when playing, you should only use money that you don’t need for your daily living expenses, and have earmarked explicitly for hobbies.
To this end, it makes sense to write down your fixed costs and variable expenses every now and then, and work out how much budget you have left over each month for playing. To ensure that this money isn’t then used up too quickly, it’s a good idea to divide it into weekly, or even daily, gaming capital.
Based on this, and taking into account the volatility of the game, you can then set your base bet, so that it’s at a risk-return rate that you’re comfortable with.
