hi,
i want to know, if i have coins, how i can stake them, What is the benefit of staking coin and for how long, we have to do staking to get benefits.
You just need to download their wallet and unlock it for staking.
You'd earn a reward when you're staking.
I'm staking 3 coins right now - Billcoin, Radium & Warp.
Let me know if you need some more information.
