I started trading small amounts of money in this platform https://www.okcoinz.com/#/pages/fund/index I’m suspecting the person that advice me to go in this platform has scammed me. I made profits but when I want to withdraw my money the system say: contact support to pay fees. Now they are forcing me to pay 30% of my profits in order to free my funds. This was said by a portal assist support channel and providing a separate wallet to pay taxes. Is this a scam? Is this normal? I tried to withdraw a time a go and succeed but now my funds are frozen until I pay this fee.
