RNDR on CEXs

I'm vaguely aware of the transition from RNDR on Ethereum to RENDER on Solana, and seemingly the RNDR token will be phased out. However, RNDR still seems to be traded on CEXs and most recently had a nice pump. As far as I can tell, most if not all major CEXs have yet to convert their RNDR or even trade RENDER at all, and no plans to convert have been announced. But isn't this token going to be worthless eventually? Is this being traded purely on speculation at this point? What's going on?

I'm bullish on Render but is there a point to holding the old token anymore?
