This is a Canadian cryptocurrency company that is a scam. When you deposit money to your wallet with them they prohibit any withdrawals for three months even if you make a good profit on your money invested. Then they have rules that make it illegal to withdraw if you have less than 0.03 Ethereum which is no small amount when you consider the current price of Ether. When you do have enough to withdraw you place the withdrawal request which needs to be confirmed by answering an email confirmation sent to your email account. The problem is - they never send the email. Then when you try to withdraw more it blocks the new withdrawal because the previous withdrawal was never confirmed by email which they never sent to you in the first place. When you ask them to close your account they tell you, you have to withdraw the crypto in your account before they can do that. But because you cannot ever withdraw they never close your account. I am reporting them to the Ontario Trade Commission to have their licence revoked.
