What is the easiest way to mine BTC for free?
Easiest and cheapest way to mine BTC would be cloud mining but you might not end up making a lot although whatever you make you will be able to withdraw it.
So I have personally used many cloud mining apps/sites and the ones I found to be working so far even today as in 2021 (almost the ending of 2021) would be Cryptotab and Stormgain.
Now I know that some of you already know about these apps and have even tried using them, so let me share with you a simple way to make it profitable for you.
Let's talk about Cryptotab first(PAID)
Download the application first, use the link below. Don't worry the application is totally legit and it'll redirect you to your app store from where you can download it, I would recommend you to always use the application from your app store and not the modded one since many people try this thing but ultimately while withdrawing their BTC they cannot because Cryptotab detects that modded version and blocks their transaction. This browser will be paid but it is really cheap, will cost about 50 INR which is probably lesser than 1USD!

Once that is done, tap on bottom left icon and start mining!
Only use the legit version from your app store in order to avoid any problems in withdrawal and avoid getting banned
Once all of this is done, look for the affiliate section which tells you to invite two users to get a cloud boost absolutely for free! That's it, use that link to get more people into mining and get x2 cloud boost without paying anything more. Usually this cloud boost would cost you at least 4–6USD so it's better this way
Now just keep checking your mining every three hours to ensure a constant, nonstop mining
Now let's talk about Stormgain app(FREE)
Again use the link to download the app which redirects you to the app store from where you can download it and guess what it's free unlike Cryptotab!

Register and start mining and you'll get 3$ worth of BTC absolutely free and whatever you mine from that point on will be added to it.
Check the referral section and use your link to get more people into mining BTC on Stormgain which gives you some of their earnings and also a cloud boost for free! Absolutely for free!
My personal suggestion would be use both to make a significant amount of BTC for free
