"Coinbase sent an email this to users this morning warning of credit card company changes that could affect customers. Changes to the MCC code for digital currency purchases could cost investors by allowing credit companies to charge higher fees via cash advances."
http://www.techvoid.com/2018/02/01/coinbase-warns-credit-card-mcc-code-changes-cryptocurrency/I got the message this morning and was surprised. I have never been one to use credit but I really think this will affect a lot of things, what do you think?
The credit card companies are now treating bitcoin purchases as cash advances - which means they charge the credit card user a $15 fee. People have been yelling at coinbase for this, which is why coinbase has sent out the email. In reality, it's nothing to do with coinbase and it's to do with credit card companies.
Moral of the story: don't buy bitcoin with credit cards. Wire cash to an exchange and then buy, you might have to wait a couple of days but it is cheaper.
