igehhh oh, wouldn't want to challenge you =D I suck big time at Betbuilder. I honestly don't believe I've ever won anything bigger than 4/1 or 5/1. I always seem to want to insist on a goalscorer bet which is actually poor value in BB.
I still have my 100% record in bet builder, you can challenge me in MM but please I would advice you to not near bet builder except you want to lose.
It's up on the thread here:

All are welcome to try it out who are still on here since there isn't much conversation now and are in it for the lulz at this point.
There is a prize of 2mbtc free bet available so it should have a bit more participants this time around.
Good luck my friend.
