Majority here are earning their iFarm tokens from tipping and getting tipped by readers but i doubt if most are making their iFarm token yield more iFarms using Harvest Finance.Its so easy at first i was scared and did not know how to go about it, but well if you really interest in something yoyu will study beyond what is in-front of you.
Step #1
Assuming you have your chain wallet set already in the setting section where you withdraw your iFarms to. So we are not getting into much detail on this step because every here has added those wallets, so lets say you withdraw your iFarms to Metamask wallet.
Step #2
You go on Harvest.finance which is the website we will be using to stake and farms using our iFarm tokens from Publish0x. After you click that web link you will see a page like this

This page on upper left shows value of deposits being invested by investors in Harvest Finance together with the monthly profits being share among farmers. Then in the mid-center there it is written Next Emission Decrease and there is a countdown showing days left.
Then on the upper right there is price of 1 Farm and the staking APY percentage and the market capitalization and the number of FARM staked.
Step #3
Just below its written connect wallet so you click there and the page i attached below will pop up and you select the wallet you want to use and on our case we are using Metamask,

After we select Metamask our wallet will be connected and we will be able to see our metamask address on top right corner and the balance of our iFarm token will be shown aswel.
Step #4
You will be seeing different assets you can stake and their APYs listed so you go on and click the FARM then it will expand and you will see this

Your iFarm balance will be shown below Unstaked FARM so you just go and click that checkbox written use iFARM because that's what we have and it represent FARM, then after you select the amount you want to stake then click deposit and your iFARM will be staked.
Conclusion
On this you can see i staked 0.214199790 iFarms and now my balance is 0.239045591 and i am going to live it on auto pilot compounding until i have a whole FARM token. Its a wise thing to do and not let you token idle in the wallet instead accumulate more through staking.
