This could be 100% scam i had seen it to huobi telegram. Some of the people showing their
PROOF OF PAYOUT, but my doubt in this kind of people are totally
BOT because most of their profile have a lack of information. It is impossible that your crypto asset will have 1:1 ratio when you invested that's completely scam. So i think this type of doubler should be avoided.
I couldn't find a link on this
