Anyone experienced that can answer??

I am based in EU and have played on Nitrogen, SWC, SportsBetting, 5dimes, from those that accept BTC, and had no problem with withdrawals (no need to send documents and stuff).

Would that also be the case with Americas Cardroom and WPC, or will I have problems withdrawing amounts of 1-2 BTC? I don't have a problem sending my documents, but I don't want to be locked out of my account with money inside. So, do they accept players from everywhere or is it only for specific nationalitites?
