The snapshot date is 12 December 2020. After they announced an airdrop demand is really high. I think that it won't last long. XRP is near to reach peak for this year and since the price has risen quickly there will be definitely a correction soon.
I have the same thought as you too. So many XRP supports were spearing the word of spark token in various places. This creates hype for ripple. I just expect the dump to happen when the snapshot will have taken.
The bitcoin cash was also getting a pump before the snapshoot for BCHN and BCHABC has been taken.
BTW im not seeing any good news related to the ripple. Could the pump become another Pnd?
We will see that in the next days.
