I do not know how to tell my wife about it, and I have a 6 month baby crying all the time. I am now soooo depressed and lost all my trust to the crypto world.
Your lost trust should be in the scammers, not the crypto world.
Learn to protect yourself (escrow) and don't risk more money/
BTC that you can afford to loose.
With a wife and baby to support playing with altcoins shouldn’t be your priority and just giving them away is (as you now know) rather foolish.
EVERYONE, get a grip and use a trusted escrow and avoid anything that leaves you overexposed should it all turn up bad!
