it remains to be seen whether SPS demand to burn for DEC will outpace the SPS inflation due to rewards payouts.
That's a very good point and it's difficult to predict that. I think it will be felt mainly once SPS staking requirements for leagues will be active. People will need to stake the tokens on their accounts and take them away from liquid supply.
It's going to be interesting I believe ;-)
Yes I agree, especially for the botted accounts playing in the lower leagues. Most of the active players in Splinterlands already have SPS staked to be able to play in tournaments, but SPS staking replacing CP requirements is going to be great for the SPS token imo.
