For Pokerfans who would like to try their luck and skill without risking their money, these sites do give real money to free entrant of the tournaments.
1. SWCPoker.eu - Free tournament every hour with 1000 satoshi reward. Quarantine special free tournament twice a day with 20,000 satoshis each. And other free tournaments for high Krill users.
2. Poker.com - Free tournament twice a day with 25,000 satoshi rewards each.
If you know any more keep on adding.
Freeroll with low rewards is good for those who want to practice poker but it does not worth the time for some other players.
But you may check sportsbet.io and betcoin.ag, as I know they are offering regular freeroll even with bigger prizepool.
I was a fan of freeroll few years ago, my best was winning 1st place on new crypto poker site (forget the name) with a win of 0.25btc IIRC but it was when BTC value is not as high as today.
