GLX and SPS tokens are technically brothers from the same parents but I reckon they are all carving out their own paths and identities. The tokens, though connected through staking can be seen to move with their own unique market trends.
At the time of writing, staking SPS token earns you some GLX tokens. I don't know the specific ratio but I know that the more SPS you stake, the more GLX you earn for staking. I believe the GLX you earn from staking SPS token is sent to your wallet every day.
Over the past couple of months, I've found myself accumulating both GLX and SPS tokens to, first of all, benefit from their generous staking APRs and also to prepare for future pumps. For me, the future pump takes eminence due to my current situation, so their importance is ranked based on the most likely to pump.
What is the data saying?
Regarding trading volume, it is safe to say that SPS token edges GLX token by some distance. A lot of the volume could be attributed to the fact that SPS token has been around for a much longer time than GLX token.
SPS token also has more investors since we can assume that virtually every single Splinterlands player holds, trades or has traded SPS token at least once in their lifetime. This adds to the higher trading volume.
In terms of actual demand for either token, its hard to actually ascertain which one is more sought after. I gues there might not be a wholistic way to verify which one is more sought after but over a short period of time, one can decipher which token has higher demand.
If we were to go by the last 24 hours, GLX token seems to be edging SPS on the demand front but that's hardly a credible metric to determine which token is garnering more demand from the community. Personally, I prefer to use buzz and media activities to determine which token is of higher demand.
SPS is far more popular than GLX token, so it is likely going to have more demand. The way I see it, the GLX community is only a fraction of the SPS community, so the sheer number of wallets holding, trading and talking about SPS makes it overwhelmingly more popular and of higher demand.
For me though, what matters most is the immediate future and from my perspective, there's a solid chance that GLX token experience a more dramatic pump in the coming months. This is not to say there's no immediate hope for SPS token but with GLG coming soon, it is hard not to expect GLX and affiliated assetsto rally.
So, while I might prioritize GLX over SPS token in the short term, SPS token could still turn out to be the more lucrative option in the long term. In any case, stake as much of either and enjoy the APR while it lasts.
