Stick around and wait for futures. Request a membership (lease or purchase a seat) at the CME, your commissions will dive rock bottom.
But that’s the least advantage, you’ll be able to trade the spread openly which is an enormous edge against any market making maintained venues.
Spot forex, you enter a position then need to wait the market to move double the spread to start to win eventually, then you pay commissions.
Future currencies, you can win trades multiple times without any market movement, or enter-exit at the same price, virtually fees free. Night and day. Game changer.
Likely when Darwinex offer futures (tentatively end of 2019 given last november webinar ?), customer service at brokers usually can support your exchange membership application. Anyway, the procedure is not complicated to do on your own and should be known from everyone. It doesn’t change anything for the future broker (commissions unchanged) but changes totally the outcome for an active trader.
