I recently started staking the coins that I already own. I found a few wallets that support the PoS system and was wondering if its worth it to buy new coins just to stake them? Is it worth staking the few coins that I currently stake?

-Reddcoin
-Potcoin
-Cardano(Soon but has not started)
-Stellar Lumens
-Espers
-Vechain
-PlatinumBar

Any feedback is appreciated.
