Of course, the idea is to reduce the risk, we know that Dec has a parity of 1000 dec = 1 dollar and right now it is not being fulfilled, there is an inflation x10 and in the future Dec will return to its original price because the Splinterlands has a mechanism to carry it out but it has not been so efficient because everyone keeps them and on the other hand we have SPS that due to the rewards of the Airdrop will surely be lowering its price until it ends or they say an important news regarding it.
Knowing the above, I personally went for the Dec:Busd pair to reduce the risk because both dec and sps have a bearish trend in the short and medium term.
