I've been testing Over Protocol for more then 7 month's and i got 75 OVER airdrop.... thry worth (15$)

But for VANA Testnet I've spent 1 day just for fun and i got 1.20 VANA. (32$)

Should i continue spending my time and focusing just on one protocol like i did with Over Protocol? F... Over Protocol 

It's great to see you exploring different protocols and getting rewarded for it! Maybe diversifying your focus could lead to even more valuable opportunities. Keep experimenting and enjoy the journey!
