Well, this market is still very new, so you must treat the investment you make in BTC as something very risky.
I also owned BTC in my webwallet in BIPS. Sure, I lost it all, but high risk does not come with guarantees and I get that and will continue using the processor services of BIPS, as I find their system easy and cost efficient.
As far as I'm aware coinbase can do many of these same things and has a full payment API built in, also a better track-record thus far as well.
Coinbase are US based. Why would I deal with US based company if i am located in Europe.
