Sur reddit:
After we contacted Bitfinex in order to list USDEX they sent us the following message
"individuals resident in the United States are not permitted to be customers of the exchange or use our services. Furthermore, United States residents are prohibited from accessing our services using any virtual private network, proxy service, or any other third party service, network, or product with the effect of disguising their IP address or location."
Because USDEX Team and Advisors are mainly US citizens and because in Q1 2018 the USDEX legal entity will be available we won't have the opportunity to buy and send USDE on Bitfinex (at least until they change the policy)
En revanche ils ont l'air assez volontaire et motivé pour être listé sur un échange avec du volume
In avec quelques ETH, paris à prendre
