i am not sure i agree, this is sportsbet contest so whatever they decide will be fair i am sure, but their contests are tailored for everyone.
0.1mbtc entry fees means they want everyone to have a fair shot and not just the big wallet players. allowing multiple entries would only make it unbalanced towards the people who can afford to enter 10-20 entries.It has always been like this, where even the small fish have equal chance to win, so like i said before would be very interesting to see how they decide this
