Nextlevel Future are 100% scammers
They are 100% scammers, thieves and trickish people. They engage you by giving rewards in the beginning, then lure you to putting your money. They asked me for extra 6000USDT, to withdraw 3000USDT, with a promise of receiving 10000USDT. That's when I realized I have been scammed, Don't deposit any money to it. They will never return your money checking their pictures online I realized all their profiles are photos from online ads.
