CUB Is Shooting Up - What's Going On?

Just as Hive account@edicted predicted CUB bottomed out slightly below $2. Now CUB is going up surprisingly fast. It's gone up 75% from its all-time bottom.

Not only is the market cap of CUB growing rather impressively but so is the Total Value Locked in all the Farms and Pools.

I think this may be to a large degree the result of deprecating these Farms (liquidity pools):

These pools were quite possibly earning more CUB which was getting dumped on the markets than they were burning thanks to new deposits whose makers were paying a fee.

These Dens (staking pools)

would allow a user to stake four different stablecoins and two different coins to earn CUB. What many users must have been doing is sell their CUB rewards for the stablecoins to increase their stake and earn more, thus driving down the price.

These are the Dens left:

I may a little dense but I have to admit that I do not know why the BTCB and ETH Dens exist. They allow a user to deposit the two coins in return for CUB rewards if they agree to pay a percentage in CUB. What is the point of the staking? The effect on the CUB price would be positive, of course, if more people staked (and paid the fees that, if I've understood correctly are only temporarily set at 0%) than were earning and selling to increase their BTCB or ETH stacks. What other utility does the staking have?

I do get the liquidity pools very well. The business logic is very clear. Liquidity is provided for the end users to be able to swap coins in exchange for a fee with as little slippage as possible, which is why you have to reward the liquidity providers.

But the staking I don't really get except for the CUB Den, which can be thought of as a temporary sink for CUB in order to reward users for holding it instead of cashing it out immediately.

Can you please enlighten me if I have missed something?
