Bitcoin trading is very cool here. I dont have to pay any commission to begin with. It is unusual since all cryptos at every forex broker, go with the commission. And considering the price of Bitcoin this commission is quite a burden I must say/
But AAFX offers not only commissionfree crypto trading but also rather high leverage. It's not that habitual for digital assets, too. Such volatile assets bear a lot of risks so brokers try to restrict leverage to reasonable levels.
Apart from cryptocurrencies; AAFX provides a wide array of classes, including a huge number of stocks. So fear not, you won't have a shortage of instruments for trading.
