To me, at least, this is another one of the many game dimensions of Splinterlands... the 'rental market game'. Just like you compete during a card battle, the rental market is a sort of competition as well.
For example, I have some renters who rent long term, some as long as 180 days! They rent early in the seasons, for an extended period of time. I purposefully do not cancel those rentals, even if I can increase how much I would get for them in the last couple of days of the season.
However, if one of those 'long termers' cancels on me right after the end of a season, I make a note of it and cancel any future rentals they make in time to re-rent them at higher prices in the last days of the season.
When I list them for rent, I list them at prices that make sense for me, on what return makes me happy. That's not always the lowest price, but mostly all the cards I want to rent stay rented.
I can see the other side from a renting perspective, but this has another side too... which makes it seem much like an additional element of the game to me.
Admittedly, I am odd. ;_
Yeah a very nice aspect of the game for sure. Good luck competing with BOTs for a card on top of another thousand players.
LOTS OF FUN!! Can't stop smiling while all the cards that could give me power are for more than a thousand DEC a day. This system is great! All the players can get what they want. They just have to be faster than a robot, GREAT!
