The only way to buy or sell SBET is on coinstore.com centralized exchange
It has a market maker and 1.85% of the total supply there so not much is needed to move the price up when buying or move the price down when selling especially when done in a 1-click. For me, it worked best to buy (or sell) in smaller batches to get most.

It remains one of the main downsides of SBET, the dividends have been excellent and super reliable for a very long time now in order to actually get invested you need to go out of your way and it's not for the average user. Once you have everything in place it is all very easy. The ood thing is that it's easy for gamblers to sign up and use the platform in a centralized way but they are held back by being on an unpopular chain. That said, everything does work very well but it's hard to see massive adoption and it's not without risk even though it has a solid history.

Good Luck!
