How Can I delete my debit card info from Their WEbsite??? I do not want it in there. NO MORE
You can't, really. You can close your account, and you can email their support and ask them to delete all the information they hold on you, but you have no guarantee that they won't just say they've deleted it but actually continue to store it. Given how generally shady Coinbase's behaviour is, I think it is more than likely that they will continue to hold your information.
How is this possible that there was no buzz in media about this insider trading and other facts @Oeleo is talking about?
The articles are there, they just maybe aren't widely circulated because Coinbase is so popular, and users generally don't like thinking they are using a scummy exchange, and prefer to turn a blind eye to the whole thing. Just Google/DuckDuckGo
Coinbase insider trading or
Coinbase Digital Currency Group and you will get plenty of hits confirming what I'm talking about.
