Want to invest here but Im in usa and cant access site any suggestions?
You have to options: either you will forget of SatoshiDice and focus on other investing options - as there are plenty of bankroll investment out there, if you like I can share with you more than dozen.
Or - your second choice is to use VPN with non-US IP and try to access SatoshiDice that way.
Same for me. How can I withdraw my funds?
It is most likely random service hiccup, wait a bit for now and it problem will persist then contact support or post on forum.
