As I know, brokers are offering the Bitcoin as an instrument on their trading platform, so you basically trade on BTC as a derivative instrument, but with fiat currency (usd / eur). On the other hand, the beetoom.com website, they accept BTC as payment, you actually trade in bitcoin. Have anybody tried it so far? not on demo, on real account?
I've made some profits on buying and selling BTC and ETH, so I would like to try something more than this - like trading with it, but I'd like to have an opinion about it.
thks!
