Yes. So, let’s assume we’re talking about a return on 1750PRV (the staking amount for a vnode.)
Constant is currently at 50%APY.
Monthly return = 73PRV
vNode is currently at 120%APY.
Monthly return = 175PRV
(This data is based on an average of reports I have seen from people posting about their vNode earnings on Telegram, in private messages, and from my own return on my 6 vNodes.)
If you host your vNode with Jservers, you will pay a fee of 24PRV/month (~$12), which puts your APY at 106%, after fees.
So, Constant charges no fee to Stake, but the return is a significantly lower APY.
Google Cloud charges about $60/month to host a node.
Digital Ocean charges about $40/month
