I have entertained using cryptocurrency for game betting at some point, while running some typical web stack. When I started looking into security and scaling, I realized there was a expensive and complicated overhead. When security is of very high concern, traditional performance seems to really suffer.
They are very well funded, and they can afford scalability. It's not that hard, given the number of transactions even at peak so far.
So yeah, I find these weird circuit breaker patterns suspicious. The worst part is "partial" degradation, when you can't execute trades, but someone else can. It's very easy to hide all sorts of irregularities behind these partial outages.
