Correct me if im wrong, but that basically sounds like a button that automatically sells or buys at market price?
I hope it means they determined that 5 days to get BTC is ridiculous.
basically they are solving a problem that wasn't there with other ways of buying or selling bitcoin(i've never used coinbase, so i don't know if this 5 days of waiting, is true)
I never used coinbase either, no i just feel like they are becoming a corp tool in order to collect data from bitcoin users and traders, i guess mainstream users feel safe that way.
