> I am lucky that about two months ago I moved over to Coinbase from both Mt Gox and BitStamp. I wonder now if Coinbase is going to start having issues.
'Someone' didn't ensure their trading engine did atomic writes to a database (by the way, that database doesn't do write isolation on multiple documents by default.. guess which database is that? Hint: it starts with the letter 'M'), which resulted in a potential race condition that could be exploited.
Coinbase uses that database, and apparently did not know that you need to ensure atomic write operations.
edit nwh links to Coinbase CEO's comment that it was not them. Ok, good to know. However, I still can't see how anyone would use said database in critical/production infrastructure, sorry. Maybe in a few+ years time it will be mature enough.
You should consider moving your coins out right now, since there's no benefit to keeping them in Coinbase unless you're trading. (This is always true regardless of the current problems.)
Not even, since Coinbase is a webwallet not an exchange... People generally keep them there because its an easy way to manage/spend them (esp on a phone)
Meanwhile I still wonder why people bother with online wallets at all. They are less secure than traditional banks and centralised. I only hold very small amounts of coins in online wallets for trading and use bitcoin-qt for the rest. Can't say I ever noticed any downtime.
