ok so it is not safe to invest?
really? you are not investing anything, you just sent money to someone from video and you were very lucky to get your 3$ back.
My friend says he been making free bitcoin from youtube and I couldnt figure out how
That address on youtube has 3 transactions worth 0.002 each...
So i paid him $50 for him to show me his technique and he showed me a game
I waited for exactly 23 minutes and checked back and saw the free bitcoins ($3) they deposited.
My friend said that he got most of profits from inviting more people
You paid your friend 50$ to earn 3$? I think i know how your friend made money, you gave him 50$! Maybe this 3$ came from your 50$? Next time think with your head, there is no such thing as free money, and you lost 47$
