That question rather sounds rhetorical to me

Bitsler and Primedice can cheat you with false and misleading claiming that you breached their terms and conditions and confiscate your account balance, like it happened thousands of times in the online gaming history!
Good point. In 2018, if they can't cheat you through games, they can easily get away with cheating by introducing all sorts of terms and conditions as if the website pays taxes to the government. I'm not worried about provable fair games as I'm with the terms and conditions.
Provably fair doesn't mean that a site cannot cheat it's players.
It means that players can prove when a site HAS cheated it's players.
A website could claim to be provably fair and still make you lose big bets and hope that players never verified their bets.
Sites have been caught doing this in the past.
Well said chief! It's sad to see you finally getting the tags over the shady betking operations.
