To my knowlkedge, this is the only broker that gives mastercard. I didn't think it was that useful at first, but as my account grew, I found it increasingly worth it. Like, it does everything a regular credit card does, but its linked to my trading acc, and I don't need to pay withdrawal fees to buy stuff with it. Online and offline. I just use it through my iPhone, never withdrawn through ATMs, but it supposedly works there too.
Prob its useful for those who want to top up their acc, but I use it only for withdrawals. I have money outside of my trading acc, of course, but withdrawing profits bit by bit over month like this is more convenient and cheap.
Swing trading XAUUSD here, and doing 1-2 trades per week tops, so its like 1-2 big profits, than a trickle of small withdrawals.
