Since I've seen what happened to Coinplay, my question was: Why we should play with minor gambling platform, and not use only gambling platform like Stake, CloudBet, fortunejack ecc. which ensure us good games, 100% of safety in terms of withdrawal and provably fair (about games)? This question is also for the owners of gambling platform, maybe they can help to reply it.
There are many reasons why users play at those gambling platforms that aren't reached the stage yet like those reputable gambling platforms you have mentioned currently. Some reasons are, they just want to test the site, they see something special on promotions or bonuses, or just plain and simple, they just want to try it.
It's not wrong to test new sites as long these users understand the risks. There's no way we can tell if the gambling site is going to be turned into a scam if this site shows no signs of turning to that stage. On the other hand, we can assume already if the site is a scam just by showing obvious signs.
If users wants to test new sites, which doesn't have any much feedback or reviews yet, they should understand very well the risks before diving in.
