A fantasy

Just in case there are still people out there who believe in the silly fantasy that 1000:1 dec will be coming back any time soon let's share some data to put that fairytale to rest.

First we should note that DEC is not a pegged token. Splinterlands has given it a PAR value via credits which has the ability to bring it up to 1000:1 DEC... but has done nothing to keep it down all the way to 1000:1

The value of DEC in the near future (for next 350 days) will be dependent on how well SPS does because of this number

And it will be dependent on the INFLATION and DEFLATION methods of DEC.
In particular Inflation via burning which has a connection to Chaos Legion packs and so a ton of what happens to DEC will be dependent on pack prices and rate of pack distribution.

Daily play inflation is gradual and self correcting... card burning inflation is a bit more of a quick show to the decision based on central planning.

If splinterlands allow unlimited purchases of Chaos Legion packs then DEC will crash to whatever the average burn ratio of the packs are divided by $2 (assumption that this is the price)

So if the burn ratio goes down to 500 dec per pack then that means immediately one solitary person can crash the price of DEC down to 4000:1 ... Notice it's not 1000:1 thus again helping people realize that dec will never be 1000:1 again because they're not likely to give discounts on DEC this time around.

Also it should scare the crap out of you if they allow unlimited pack purchasing because it will crash prices all over the place where as a limited gradual release would not do this. However if for some reason you want DEC to be lower then maybe you want a million packs to be burned and that's likely what it would take in order to double the supply of DEC and There is evidence you would need to have way way more DEC than that in order to be a spendable stable currency for an ever growing player base.
My guess is you would have to burn 5 million packs... in the meantime we're also printing 200 million dec a month at present rates so that will have a significant impact. (And allowing one rich person to do that all themselves will make no one happy)

I am not saying DEC will go up in value. I think splinterlands will not allow unlimited CL pack purchases and the price of chaos legion packs on resale will be above $2 and not a ton of burning of cards will happen and cause a huge impact on price.

I think DEC will come down in value gradually because we're printing 210 million DEC a month. And soon it will be enough liquid tokens to handle our purchasing needs.

However we have a lot of burn methods and many many millions get burned on DICE packs and guild upgrades and soon Rift watcher packs and 2x the number of buildings that cost millions of DEC for each of the guilds. So that makes you realize why even with 5-7 million dec a day for about a month we are still only at 489 million DEC in circulation (according to hive engine... which btw I strongly believe is wrong... i do not think it counts DEC on any other blockchains)

BIGGER EVIDENCE 1000:1 IS NOT POSSIBLE

Today there were $279k DEC in market purchases and $28k in rentals
If we were at 1000:1 that means 62.7% OF ALL currency in the entire game would have to have been used to make those purchases.

Not gonna happen.
83 million are in diesel pools
59 million in bsc pools
71 million in uniswap pools
That's 213 million if you add 307 million that's more DEC than even exist.

This is practically impossible for DEC to be worth 1000:1!! I know the people that own a lot of that DEC and they're not about to take it out of the pools and forgo their SPS drop... but even when the airdrop is done do we really expect it to still be enough even if all the pools go away? Do we think Splinterlands will let the pools go away?

SCENARIO

DEC will take a long long time if ever to even consider 1000:1 for more than a moment.

If it does go down to 1000:1 this is what happens.
Players earnings are cut by 7x and players leave splinterlands in droves that came here to earn money by playing. UNLESS sps is worth a lot of money and splinterlands is giving it to users for winning games in which case holding DEC to get that SPS from airdrop or from adding to an LP that offers SPS will mean DEC will have buy pressure that keeps it much higher than 1000:1
If SPS earnings from playing go up then more people will buy cards and rent meaning the demand of DEC goes up... this means prices go up.

If earnings instead go down players leave and players earn less then rental market dies down because of both those reasons. If renters can't rent at good rates they'll likely just sell cards... thus crashing both the rental and buy market prices.

DEC at 1000:1 isn't a fairytale ... it's kind of a nightmare.

Anyway if you have some math to dispute this I'm happy to hear it... I reserve the right to have not thought about something and I'll change my mind if you have a great argument.

RECAP
DEC won't go back to 1000:1 but it also won't keep climbing forever and daily winnings inflation will start to have an impact. Also 300% apr on DEC for airdrop will likely keep it high for a decent amount of time despite the inflation... and finally the choices of Chaos Legion sale will have a MASSIVE impact on the price of DEC. (aka watch out for the possibility of unlimited pack purchases)
If SPS crashes or player base goes away and people stop renting or purchasing then there will be very little demand for DEC... then yeah 1000:1 IS a possibility... but Like i said it's more a disaster possibility.
