Sorry, it has been a while - I'm only just revisiting this.
Thanks for this.
I'm not 100% sure I get it, though:

Would this be the most interesting step-by-step course of action?
I swap my DEC for SPS in-game
I move SPS to my Metamask wallet using the BSC chain bridge
There I use Metamask swap to swap the SPS??? (Any idea what to swap to? Does it matter?)
I export the new token to my exchange to cash it out?

8 years in SPL and I never had the need to cash out. Meanwhile, I haven't been paying atention to anything crypto related in about a year, and it feels like I forgot everything I ever knew 😂

Another problem is I can't get the support part of the Metamask site to load - it triggers my virus scanner, which makes me wonder how much I can trust Metamask itself (I used it in the past, but that has been a very long time ago)

Any advice would be welcome
