Put simply, Betfair Pools offers bettors the chance to bet on the outcome of football results and scores. Amounts staked are placed into a big pot (or 'pool') and the winning players share the total pool, minus any deductions.
What kind of deductions could there be and for what reasons?
Regarding the €1 entry offer for the Bitcointalk community.
In my opinion there seem to be too many steps to be eligible for the offer. Why is it a requirement to follow you on twitter and have a twitter account?
I know you are trying to boost your social media presence but I am sure that many users here are not using twitter or want to use it for whatever reasons.
