How many people use Wirex?

Could you provide me with some insight into the user base of Wirex? I'm particularly interested in knowing the approximate number of individuals who actively utilize their services. It would be valuable to understand the scale of their platform and the potential reach they have within the cryptocurrency and finance landscape. Do they have a significant user base, or are they still relatively niche? Any information you could offer on their user demographics or growth trends would also be greatly appreciated.
