Coininvest is a company specializing in precious metal trading, selling metal coins and metal blocks, but I haven't seen any information about regulatory licenses. Is this company reliable?

no hemos vistio ninguna denuncia contra esta empresa coininvest, pero tampoco podemos confirmar que sea una confiable, ya que no tiene ninguna regulación efectiva...

They changed their price of gold coin and gold bars arbitrarily, and I don’t think it is a trustworthy broker. Anyway, I don’t have a pleasant experience here…

詢問提現的稅收機制，結果私自開啟稅收機制，強制消費者繳稅，否則無法出金甚至凍結帳戶。
