I encountered an individual online who persuaded me to invest in http://www.defi-uni.com. Following her advice, I transferred $1000, which was then converted into USDT. When attempting to withdraw my funds, I was informed that my account was not activated and was given two options: transfer an additional 500USDT or wire an extra $1000 to activate the account, with the assurance that only then could I withdraw my funds. Having already lost $1000, I am reluctant to send an additional $1000, as this request seems unreasonable.
