It's hard to prove with free money then we will have more wins in betting because on the basis we have a small chance and it might take a long time to be lucky.
So whatever it is I have never felt it with free money can be success like that which just deserves people will not be strong in doing tricks of this kind, which I know in gambling still need big capital to win it.
It's a very small percentage that people will profit from free play, it is only allotted to familiarise in the platform. Those who are really able to win and gain profit from it, a huge one maybe 10x higher from their free is indeed really lucky since mostly who used their free plays just lose in just one day or few games.
