This is scam bookmaker. There is no decentralisation.
Dexsport is fully centralised sports betting platform and casino.

All withdrawal requests are processed manually. The withdrawal option is constantly closed, and they do not fix it until you contact them. I have seen many complaints about this.

They can return any of your bets without explanation.
I definitely do not recommend playing here.

My withdrawal request has been pending for over 12 hours.
