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:

If it is plain double your ETH, that is certainly a lure or a bait to a likely scam. If there are certain terms and conditions and other complicated rules to make sure everything is sustainable and that the profit will not be taken from other new members, there is a possibility that it may be true. But from the information that you presented, I would conclude that it is a scam. Stay away from it.
