In sports betting specifically football is your decision to cash out or wait it out until the end of the game based on the opinions of other people if you shared your bet slip with them while the game is on?
Some people after they have placed their bets on several games may be so excited to share their bet slip with their gambling community who helps to monitor if games they bet on are winning or they are losing. In some cases if all the other games were a win and it remains like two more games on the slip, they may feel pressured to cash out based on the opinions of their friends. In this case do you give in or hold out based on their opinions?
First of all, i don't like the idea of sharing your betslip with some group of friends except you want to share the betting code to anyone who might be interested to bet along with you. Showing others your betting slip for them to monitor the events you staked on is unwise to me because let's assume you placed the bet to win huge amount and you just exposed your betting slip which means if peradventure the bet wins, those people you share the bet with will begin to to campaign your winning to the community which may pose security threats on you.
Now coming to your question, sharing your bet slip to a group of people means that you have to agree to whatever suggestion they give to you like in cashing out a bet that is left with few events before all the bets are confirmed and if you don't obey their suggestion and the bet loses, they will call you all manner of names like calling you a stupid or a foolish person for not cashing out and if you also harken to them and cash out then all the events plays accordingly you will blame them for giving you the idea of cashing out when some events has not finished playing. However, we should not be so greedy about getting all the possible returns in a bet, if an option for a cash out is available you can do so and use part of the money you cashed out to stake the remaining events from the bet you cashed out.
