In the end, what I assume is really happening behind the curtains is that packs are going to be sold for $2 in fiat again or in DEC, but not for 2000 DEC. You'll get to purchase them for 250 DEC or 200 DEC instead. That's why big holders aren't selling DEC, how the renting/guild brawl system helps them so much and the reason behind DEC prices are still going up. There wasn't enough DEC to meet their plan yet.
I assume it's safe to buy DEC for now, specially because of the SPS airdrop. If I want to invest more than $50 in Splinterlands, I'm probably better off buying and holding - not necessarily playing. I'm holding/staking DEC/SPS so I can get packs without having to buy them off other people (who are going to sell them for an even higher price). It should be near the peg already so I don't think it's risky.
This does make older cards seem less useful, though, so I'm probably not going to buy them ever. I'm kind of glad I sold mine. I'm not an official investor, I just use my brain. It might be the case that I'm right and I'm calling the exact thing older investors aren't trying to incentivize because it's profitable for me while hurting them (so roles are reversed). That would explain some people lying to me and trying to convince me to pack up and leave.
At the moment, there's a big gap for new players that needs to be filled. I'm taking the initiative which I'm detailing in my next post. Hopefully that will increase player retention in a way that's fun for them. Obviously, I can't accommodate everyone, but I'm sure those who are interested and I can work out something together. More details on my next post.
