Exeedme - Cryptos that have betting as one of its underlying features

Salamu Alaykum everyone.

With how hot and popular NFT cryptos are at the moment.
Can anyone clarify on halalness of investing in cryptos like Exeedme.
Exeedme is a blockchain-powered tournament platform allowing gamers at all skill-levels to monetise their skills.

1:Earn by Winning.
Challenge friends or let matchmaking work. Set the stakes and fund them with liquid cryptos. Winner takes it all.

2:Earn by Engaging
Whether a gamer wins or loses, every time there is a bet on your skills, you are game mining a $XED reward.

3:Earn by Progressing
By staking $XED, players unlock NFT rewards which grow in exclusivity and rarity as they grow their ranking position.

What im worried about is the “betting” part in these descriptions “Set the stakes and fund them with liquid cryptos. Winner takes it all.”

Can we invest on this crypto if we do not take part in that particular betting ourselfs?

Jazakumullahu Khayran for any responses.
