I used coinbase sometime but I didn't had to have any transactions from it but most of the people are using it and trusting it.
I had read somewhere here on forum that someone got problem with his account and it was disabled by coinbase.
But upon reaching their support and giving few questions to the owner, the owner answered correctly and promptly.
Coinbase did retrieved and gave his account.
What? You're using coinbase (sometimes) but you don't have any transactions through it? How is that called using?. Coinabse is a really popular web wallet especially when you're new to bitcoin.
Then what happened to others who complained? Sorry to say but in this kind of industry, You don't easily trust someone. Right now, I am 99.9% of not usingg coinbase. There are many web wallets out there. I won't stick to the one who has a 50-50 Positive and negative feedback.
