Man, it's not late at all. You can still earn SPS airdrop by playing up your rank, holding dec and holding SPT and what not... Everyday you will get more and more if you keep at it. Stake those SPS inside your in-game wallet and earn APR too.

Invest in some good cards or maybe pick them on rent from the market. One golden card is making me 200 DEC per day just from the rent. Since we are nearing season end. Players are going crazy and doing everything they can to maximize this opportunity.

It will be too late after a year or so. Splinterlands has already planned a lot of things. So hop the train before they come out.
