Fake news. Quadrigacx has been in the space for a long time and I’ve not heard of any issues with them. It took me maybe a day before I could start trading. It withdraws through my back account.
I spoke with my rep at TD Bank and they said they’re basically only concerned about people buying bitcoin to pay for ransomeware or being conned out of their money.
If you’re Canadian, don’t worry. It’s easy to get started.
