It can go up, sure, but it will go down as well. Anything else is just lies, so I seriously hope you edit your post. Made another reply that highlights all the problematic parts.

"If Ethereum started giving out staking rewards would you call that a scam?"

If Vitalik would say that eth would only rise in value, yeah, I'd say he's a liar as well. Staking in itself isn't a scam though.

The token itself might not be a scam, I don't know is the platform itself promising their token will only go up in value or is it just you. What you're saying here makes the whole project look scammy though, so I'd edit your post for that reason alone, since you've said to have invested in it.
