can someone check this site? about the 2x fold prize of ETH.
if someone sends 0.5 ETH to their address & will get a bonus 2x = 1 ETH
https://mixineth.com/2x bonus will be sent to the address that you entered or that you want from ETH.
Are gifts like this true?
EDIT:

i am not sure they will send you back with 2x bonuses. it has high risk to do, if you do it maybe you can lose your 0,5 ETH.. please do not believe everything that requires the payment of balance because it has risk of scam. better you can choose another way like join airdrops or bounties it will bring profit than you sent your balance
