Staking very popular and in demand when cryptocurrency market rise. During the rise of the market many people earn more income for staking but whey cryptocurrency market falls many people stop staking and sell their assets.
Honestly I don't think so, most of the stakers just let their investment in the staking platform, some of them are set in long period of time so they need to wait for their investment to get unlocked before they could make market movement.
I think majority of the stakers with huge sum of money are just waiting for the next bullrun instead along staking their investment further, since otherwise it just gonna incur losses.
