Having a gambling site native tokens may trend in the upcoming bull market when we will see some huge gains by the existing gambling sites token and other online sites such as bitvest might think to come up with their own token. Having a token gives another edge to the sites as people invest in those good gambling sites token and the sites can generate good income by selling their tokens and developing some interesting use cases for those tokens on their sites.
I have previously invested in four different gambling tokens. One turned out to be a scam, another one died quickly, and two others got dumped and their price took a nosedive. I'm sure the thought has crossed their mind but doing it in a way that doesn't result in disappointment would be hard to pull off especially in a period when small cap altcoins are struggling as Bitcoin's dominance has been increasing for many months.
