Most likely, everyone has their own reasons for becoming an XS.com customer. But for me, it was the choice of assets and opportunity to open trading account with no spreads (almost) and with low fees.
Fact is that I chose broker that is most suitable for my trading strategy.
And combination of large selection of assets and such trading conditions makes my trading really profitable

I become a client of this broker for many reasons. I was influenced by several at once.

These reasons include that broker is loyal to newcomers. I noticed this because XS has special accounts for novice traders

Broker also has loyal minimum deposit requirements.
When I opened account, it mattered to me. I couldn't spend a lot of money on trading, so I chose XS. Broker simultaneously has small minimum deposit and high-quality services.

And finally, it was important for me to get the same trading platform as those traders I subscribed to
