this is the point!
I believe the same, it's much better to use your energy constructively in the world than to employ it in a destructive way
after all, some say that there is no bad marketing... even if you bad mouth your competitor this may have the opposite effect of what you expected and blow up in your face, by making their name more available in people's memories, as an example.
Sometimes, some methods of marketing are actually bad strategy most especially in this type of marketing where a competitor tries to discredit the effort of their fellow business colleague all to adopt the clients if their weak devices of bad-mouthing kill their opponent's business.
I have seen a few scenarios play out that way I several times, but I am sure this method can not work on an established platform like Duelbits since the casino already build a good and loyal community for the business over the years and anything negative will take time before it can work and most time they don't work anyway so this marketing strategy is a failed attempt already.
