IMO, gambling and gaming industries have made a lot for cryptocurrency adoption as alternative payments. The first boost of usage Bitcoin received after Silk Road site’s launch. Yes, the site was connected with illegal activity, but we can’t deny the fact that due to this site bitcoin saw the rise. The same thing is happening with gambling sites. Playing casino games is considered negative because in some cases it can lead to addiction. Taking into account that gambling goes back thousands of years, it was initially designed for a fun past time. I think the adoption of cryptocurrency by casino sites and games of different types is good for crypto spreading. Unlike bitcoin investors, gamers use crypto no matter what the current price is, but because it’s a more convenient way to pay.
