$POLK - PolkMarkets - Is it permissible to invest in token

Assalam Aleekom,

I’m invested in this token but the more I read into what they have planned with the Prediction market the more I feel this is like gambling. They have other uses for the platform as well but I just feel I want to be sure 100% before the project becomes more popular and I get any profit from my investment.

Can I get some advice on this and if I should sell my position and leave this crypto investment.

Thank you very much for your time.
