Please stick to the staking plan it is there for a reason. You may wish to revert the 4,6,8,12 to just 1-2-3-4 points for ease. The lowest bet is 4 points and the highest are 12 points.

 

12 point bets are rare. Generally 3-4 in a month.

 

There is no opinion involved in selections it is just maths. Feel free to use the exchange wherever liquidity allows.
