I found a site called mybtc.ca which has an interac service, and claims to be accepted by all Canadian banks. Are they legit?
mybtc.ca is on the list of platforms that Canadian citizens can use to purchase bitcoin, but its cons are high fees and KYC requirements. Here is a list where you can find some other recommended sites >
https://www.buybitcoinworldwide.com/canada/But there is no need to run away! There are still millions of ways to buy bitcoins. Buy a US dollar with a credit card using Payeer or PayPal, Then transfer this money to exchanges (in case Payeer Deposit) or find people who accept PayPal in exchange for cryptocurrency like many people in this forum.
It's Payoneer, not Payeer. Officially, Payoneer does not allow its customers to purchase cryptocurrencies through its services. Unofficially, you can always risk it and see if you get away with it. PayPal doesn't allow you to buy crypto either. They are offering a service for US citizens only that allows them to purchase an interest in bitcoin, but that is not a real coin. You can't withdraw it or send it to your own private wallet outside of PayPal. You can only exchange it back to fiat on PayPal.
PayPal transactions are reversible. You better make sure you trust the other party if he pays via PayPal that he wont make a chargeback.
