Wow! it seems that SimpleFX has been steadily gaining a prominent place among the Forex brokers involved in the cryptocurrency market. I see a special enthusiasm in SimpleFX for attracting new traders by giving many facilities for the potential investors.
For my part I have been quite loyal to Etoro and Instaforex over the years in the subject of Forex Trading (although in this thread these brokers have not deserved any confidence). While I recognize their laudable efforts to get involved in the crypto market, their efforts have still been very hesitant. Etoro already has six cryptos and just this September 3 added an addendum to its terms of service by which the trading of cryptos is already real and direct, being etoro only an intermediary. In this way they stop charging the fees they used to charge when implementing the trading of cryptos as CFDs.
In the case of Instaforex, they have just included Ripple among its crypto options (BTC, ETH, LTC and now XRP), but always as CFDs, with very expensive spreads, inefficient platform and high commissions. Nothing advisable for trading altcoins.
Etouro is not listed because they don't work with crypto deposits/withdraws
Instaforex is marked as scam by ForexPeaceArmy:
