It is based on trust and a valid registered company at the Dutch chamber of Commerce (and a contract).
I've done trades in BTC for a total near 300k in the past on this forum. Some shows in my trust rating, and hopefully their are also people here on the fprum that can bouch for my previous webshop (usbminers.nl ) that was one of the biggest webshops in Holland for the mining community. Their are forum members here that have ordered for over 50k at my store in the past.
What if the company goes under? The investors would then be out of money and you probably have whatever is left after the company is dissolved or after going bankrupt (since it would cost more than what is given to go to your country, file in such courts, etc). Trust alone, imho, isnt enough in this case.
