Newbies need to understand that no such website can double their Ethereum or any other cryptocurrency. If that were the case, the value of any cryptocurrency would not be so high, because everyone would double it instead of buying it. It's just a trick of scammers so that they can scam people. Therefore it is wrong to believe any such website.
Yes, but as as newbie, I will not be surprised if someone fall for this trick, I was one of the victim in early 2017, Lol, I'm ashamed but that's what experience tells you, actually I got my first pay, but then continue to roll until I didn't get any payment and the website went offline. It was not a huge amount thought but at least I learned a very valuable lesson that time that there's no such thing as doubler. So we must continue to tell newbies about this scam tactics and it's good that a lot of members are doing it in this board.
