I invest some amount of USDT TRC20 and i see the profit every 12 hours as they promise. Later the add me a bonus of $1000 in my account without my concent. Later I plan to withdraw the amount that I have invested along with the profit but I cannot do so because I have to invest another $300 to activate the account and the bonus. Till now I'm stuck here. This action sounds suspicious. I think its a scam.
