Being a pioneer in the space is sometimes hard and playing Splinterlands is in a way being just that.
NFT's are a whole new cardgame
We are seeing things pop up that are just the beginning of a whole new economy.
If you are just playing your own cards that is fine and dandy but on the sidelines of this there are people who are creating whole businesses.
If you check out this video from @nealmcspadden he mentions that his projected income for the whole year would be more then the total of his SP holdings which is over 10,000 dollar. Now that is starting to look like a decent passive income
If you look at the post from @aggroed he talks a bit about his income at the end of the video but is making more by renting cards then by running a top20 witness
Personally I do not have that many cards but I did have a few Beta cards over and was not able to reach lvl 7 in summoners on my main account which is now sitting comfortably at lvl 6 summoners and reaching gold1 or diamond3
So I was able to put together 3 lvl3 summoner decks and now have a fourth ready with untamed summoners.
On average the accounts seem to be producing 3000 DEC per week which is at current rates roughly 2.5 dollars.
2.5 X 4 accounts = 10 dollar
10 dollar X 4 weeks = 40 dollar
10 X 52 weeks = 520 Dollars per year.
I also have some cards that are rented out on peakmonsters and @jarvie also posted that the market was growing there. My cards do not get rented out much and its only a few steem here and there but its better then nothing. For the moment I have not put that into my sheet since its really low revenue.
So for the moment I am taking all the Steem rewards and the DEC rewards I am getting and pumping them back into Splinterlands to buy orbs, mistery potions and packs. Also slowly getting more individual cards and summoners for a 5th deck.
I have also activated my starter pack on an alt account to just play till bronze for the extra 7 cards occasionally.
