This is indeed a scam though they don't admit it. I invested about $300 dollars for my 'signal provider' to start trading using my account. Upon withdrawal ($7801) I was asked to pay Capital gains tax($1,794) at a high rate which is a very large percentage of my withdrawal at the time. I did my research and discovered that indeed capital gains tax is paid on cryptocurrency so i paid it then i was charged VAT for late filing about ($1,001).What i found very strange is that they insisted that I pay money to a specified bitcoin address rather than deduct the charges and fees and pay me the net balance.
