the only platform that you can use BTC exclusively to fuel your trades in fiat currency pairs, commodities, stocks and indices.
So can you pls explain how it works? There is already a bunch of forex brokers that trade BTC / USD pairs (and I belive ssome other cryptos like LTC too). So if I get it right then your platform either exchange BTC to fiat for trading or trade bitcoin directly to commodities / stocks. Both options are pretty unclear to me at that moment, maybe there is also another options that I haven't noticed.
So you basically are able only to deposit/wd BTC. Thank in the platform you have derivative instruments CFD-like (Stocks, FX, Commodities) that you can trade. Your balance, trades, profits/loss are all in BTC, even the prices you can select them in BTC denomination. So instead of using FIAT C. to trade like a $1k account trading Stocks making/losing x$ here u do the same but you either win or lose BTC, depending on the results of your trades.
