I've got some questions:
1. How anonymos is it? Do you need to share private data?
2. What about legal aspect? Is it totally legal the way it works?
3. Do we have access to all stocks from traditional stocks?
4. Can you trade minerals like gold, silver, plats etc?
Thank you in advence!
Some answers:
1. You do not need to send any doc. (no KYC), you just need an e-mail and a nickname.
2. It is legal but unregulated, the idea is that since BTC is not consider a financial instrument, also the instruments traded and the whole system is unregulated. But legal.
3. All the major stocks in US and many from Europe are available.
4. Gold, Silver, Oil, cereals are available. Basically all the major commodities.
