After some amount of time in 50/50 there should be a function to take your bet back.
Example: You place a bet. 24 hours later, not taken. I feel that you should be able to take your bet back after some amount of time.

(*Not taken.)
But yeah, that would be a good idea. I've seen a lot of people who are getting upset and going on chat and places and whining because no one has taken their bets, and then begging everyone to take down their bets for them. So this would probably help them out, and cause less annoyance for other players. I am 100% behind this. 10/10

we used to be able to take our bet(s) back, but couple of years ago, someone found a way to abuse (glitch) it cause more coin to enter the game, so Da Man make it so that you can't take back your owns bets anymore.

so at the moment there only 3 choices...
1. if you afraid of losing of coins (or whatever you betting) and dont want to wait until someone takes the bet(s), then dont bet it in the first places

2. gets a friend to takes it downs for you

or

3. wait until someone does takes the bet(s).

Oh, I didn't know there was a bug. Probably happened when I wasen't playing.
Well if Coders could find the source of the Glitch, they could patch it. Then this suggestion would work.
Well the purpose for thiis is to lessen all the "Bets Up" in Chat and other people buggging others to take their bets. Like Shinxy mentioned.

Well if then how about taking back poke from racing
