Hmmm... It is the token of the splinterlands socmed(I think??hehe) It is also in the computation of collection power for daily sps distribution(long long time ago), 4spt = 1CP. I think that's the most value of spt. But now you can exchange it for other crypto or stake it to earn more spt when you vote.
