I think the vast, vast majority trust it a great deal, perhaps more than any other crypto property.

So I'm wondering why you would ask such a question?

They have developed a reputation for having poor, unresponsive consumer support. Try doing a twitter search for @coinbasesupport. At any given time, it's a horror show.

I personally discovered this after a time sensitive transaction took about 48 hours to complete because of a buggy deploy on their end. The only reason it didn't take longer was because I was able to track down a coinbase support employee on the bitcoin reddit.

Same. They accidentally repeated a buy I'd made 5 or so times-- and it took almost a month for the coins to appear in my account.

I ended up making a couple bucks off the deal. But I can't help but think how badly it could have gone.

Official Coinbase support is non existent in my experience. There are people on the Coinbase Reddit page https://www.reddit.com/r/CoinBase/ who seem to be able to move things along if you aren't getting any support from Coinbase.

So this seems to be a pattern. The link that I posted elsewhere in this thread and the occurrence there was precisely because of poor support. (Again, I'm not affiliated with that guy in any way)

As long as there is not a large crash currently happening, their service works pretty well. Generally, once your funds are dropped in Coinbase, you can transfer to GDAX, purchase what you want, then immediately transfer to a wallet or another exchange within minutes.
