A mining result will depend on what mining machines you are using (
and also how much mining machines that you operated). Mining software isn't giving you much different on the mining result.
So, I can say for sure, what you heard was a big scam.
"mine in 5 mins and you get 1 to 3 Eth."That must be biggest mining farm with a ton of mining machines.
In short, to summarize what the guy above said, what you described is a
SCAM.The lack of common sense is quite disturbing if you ask me. If it was, everyone would be rich, wouldn't they? In mining, and probably with anything else in life, there is no such thing as "free." Don't let your daydreams distort reality. If it's too good to be true, it probably is.
