Scammers give giveaways and force you to sign up in their website to withdraw your BTC. Then start to ask for depositing BTC to release yor money. They start with 0.01 and start increasing the amount as you insist to take your money till they ask for 0.20 BTC and more. Noting that you may need to deposite the same payment so many times as they always claim that their system didn't recognizer your payment.<br />
They've forced me to deposite 0.60 BTC so far and they are not allowing me even to withdraw my money<br />
They are professional scammers.
They change the price of the tokens at the moment of you click on BUY. This change exceeds 500%, and once you buy, the price drop back to the price you wanted to buy from.
