It's pointless for any serious tipster.
Because if you read the fine print, almost all of those sites are requiring picks to be exclusively published on their own sites.
And $100 is ridiculously small. Google Tipster Competitions and you will find sites offering thousands every months. Still the fine print is picks to be exclusive.
Yeah $100 for a month competition is not worth for me , you can find many fiat sportsbook offering €1,000 up to €3,000 in prize, unfortunately there only few bitcoin sportsbook offer this tipster competition.
For bitcoin sportsbook Directbet.eu have succeed held 5 period of tipster competition and the prize well worth enough for participants.
you don't need any rollover for withdrawing your prize..its free prediction..every month.just want to let everybody know if they are interested in free contest
