You should provide more details about the trading competition you are talking about. what kind of trading competition is that? which exchange holding that competition and does that require trading with real cryptocurrencies or will provide demo coins for trading?
I am not a trading Expert, but I do trading occasionally, and whenever I see a good signal or suggestion I try to follow that with as much money as much I can afford.
This topic is from August, so the competition will have ended a long time ago, but given the value of the amount, which is 2,650,000 USDT, it is most likely a scam because competitions like this will have enough ads and will not need referral links or pyramid marketing.
