Normally I'd tend to agree. But for those that aren't aware Bter seems to be very trustworthy. They admitted responsibility immediately after the Nxt theft. They were communicative on the nxt boards all throughout. Even now Bter is active on the nxt forums talking about the current fees and negotiating a deal with a Nxt whale to borrow 4 mill Nxt which they would then lower their withdrawal fee and payback in 6 months. Chances of Bter not following through with XCR escrow is about .01%
I agree with this; Bter were dumb to have such lax security, but in very other way I've been quite impressed with how they handled this, and also by how they helped the NXT community when one of their developers was hacked. I think they will follow through, and I'm also happy to keep trading with them.
