As stated in previous post, you'll not earn money directly with staking. Staking is like mining, without need to have expensive hw. As with mining you'll get additional coins which you stake. The difference from mining is that you actually need some (more the better) initial coins you would like to stake (some kind of "seed"). The % interest depending on coin, they can vary from 5% to 30%, that is for coins i stake. I believe there are coins that have bigger % out there.
Excellent answer in a thread full of shitposts--I'll probably give you a couple merits for this post even though your account hasn't been active since 2018.
I've been staking PIVX for just over a month now, and I've so far earned 4 PIVX. Not too bad, except that the price of PIVX is really low right now and most exchanges have suspended trading because of some wallet issues. It's a pain in the ass that I have to leave my computer on 24/7, but I'm having fun experimenting with a PoS that's earning me a little bit of interest. My plan is to set up my PIVX Stakebox that I bought a couple days ago. I don't have it running yet since I don't have an internet connection through an ethernet port, and I don't think my local wi-fi signal is strong enough for the Stakebox receiver. When I actually get internet service from my local provider, I can leave the Stakebox on 24/7 and just forget about it. For those who don't know, it's basically a Raspberry Pi with a staking PIVX wallet installed. Pretty cool device.
Even better is NEO, another coin I've fooled around with recently. It's much better than staking PIVX because you don't have to have the wallet open all the time, and you can claim your GAS every 5 minutes. I'll probably be buying a lot more NEO in the upcoming weeks. The price has tanked, and I see it as a great buying opportunity.
