Sounds interesting but is it withdrawable? If not I think its a waste of time for sure by the way some other exchange was offering it before but suddenly it was not withdrawable and the exchange was retracted all its first guidelines regarding the program thats why its a useless form of a marketing campaign. and truly a waste of time. let ask you for last time have you withdraw some Free USDT on Bitoffer yet?.
Yes for sure.
You can check the announcement from Bitoffer website:" 50 USDT Bonus can be released by depositing and trading. Every 500USDT options trading volume happens on your USDT Account, 10 USDT on your bonus account will be released."
Notice that it doesn't mean you have to deposit 500USDT, once your trading profit/loss achieve 500 USDT, the bonus can be released.
That's how I got my USDT back, hope it will help!
