On the 30th of July, I had got the reference of Mark from an acquaintance with regards to investing in cryptocurrencies and forex markets. I was asked to purchase bitcoin through an intermediate exchange www.cex.io and deposit to the trading wallet address. I did that conversion and then transferred the bitcoin worth 2.5K USD to the wallet address. After this, I was told to create an account with euroztrade.com which would reflect my account balance and it did. Once that transfer was done, I was told to transfer another 2.5K$ as the minimum to start the trading was 5K$. Hence I did the same process to transfer the additional 2.5K$ to the same account._x000D_ After one day of trading, the account balance showed an increase of 3K$ and I was asked I would invest more to get more returns._x000D_ I mentioned that I would only invest next week however, they kept pressuring to invest immediately as they had already stopped trading on my account since I wanted to increase my investments and profits. In a sense of urgency I could only transfer 3k$ to the new account and thought that would also be enough, however, even then I was told that the minimum needs to be 5K$ again and only then the trades would start on both accounts._x000D_ When I said that I am not interested in the new account and the increased profits so I can withdraw that, I was told that now nothing is possible unless the account is funded. When I tried a test withdrawal by emailing the broker, that was blocked and they did not process it._x000D_ I did also message that there is no broker that does not allow to withdraw funds, however, they just kept everything blocked.
