haha probably because most people don't share how much they make in the Bitcoin space. I suspect there are people that make that every day!
I am definitely not qualified to answer your question properly. Other than save up the capital required to get $1,000 in interest a month from some relatively non risky investment!
this is the problem I don't know what are non risky investment, can you tell me at least one where I will not lose for sure, I lost in scams about 500 $ , and I am afraid to invest now
Again I really can't give you an answer. For crypto investments any investment where you do not have full control of your private keys is risky. So unless your Bitcoins are in a Trezor you are not safe.
My approach (for Crypto) has been to put relatively small amounts of my holdings in casino bankrolls, Poloniex for lending and now Steemit. So I diversify as much as I can and limit my exposure.
I literally show everyone where my Bitcoins are here if that helps --> https://www.bitcoin-millionaire.com/my-btc-wallet/
