Actually in myetherwallet scam, I am one of the stupid bitcoiner that being scam. They sent an email as the same as the email of campaign manager at bounty asking for my info like KYC and asking my private keys.I thought it was legit because campaign manager was always sent an email update to me. So next day I found out that my coin was stole. So I can say that scam is the biggest crime here in cryptocurrency.
That was too gullible of you how can you get an email requesting for your wallet keys and you responded to it, no bounty campaign manager will ever ask you for your private keys unless he have the intention of scamming you. No one have to right to ask for your wallet private keys apart from you.
