I opened a Coinbase account. I entered a credit card to use for purchases. None of the purchases will go through. Try to contact them...JUST TRY!!
Seriously, has anyone found that Coinbase sucks this badly? How can something this poor be the first big one to go public? I mean holy F...
You are not the first one to experience it though, way back 2018 I wanted to purchase in Coinbase and all of the credit cards I used is rejected. So I was so frustrated that time, look for alternative crypto exchange and as much as they are one the top exchanges right now, they still sucks big time.
And most of the time they will be down like for maintenance when the price of bitcoin is on a massive rally. Many people lost potential profit because of that. Just try other exchanges like Binance or Kraken and see how it goes for you.
