So far as I know, no one was able to successfully withdraw BTC via Weex. I've tried to deposit BTC from Ripple to Weex following their instructions. BTC just disappeared from my Ripple wallet and did not appear at Weex account.
This explains the discount I guess - you can withdraw Bitstamp BTC IOUs, but Weex BTC IOUs are mostly useless until this issue is resolved.
Just tried to redeem a 0.02 Weex BTC IOU. No response. Redeeming Bitstamp IOUs happens in seconds.
If I am in a trust circle with someone who's extended trust to both Weex and Bistamp, does that mean I can use this person to transfer Weex BTC IOUs to Bitstamp on a one-for-one basis?
