As many of you probably know, Wirex is an app that offers you a free debit card you can fund with crypto currencies, and if you sign up using a referral link, you get $15 (an ad today said the current reward is €15 which is closer to $17) worth of their native token, the WXT, which their blog here: https://wirexapp.com/blog/post/what-can-you-do-with-wxt-0370 says you can spend using their card.

That is a lie
In reality, you need to exchange your WXT to something else & fund your card with that, but they only tell you that if you contact their support, the smallest exchange allowed is $50 USD, meaning you need to either buy the remaining $35 worth of WXT to exchange it for something else, or deposit something else into your account to exchange for WXT to reach the minimum exchange from WXT to something else.

Or you can get more WXT by getting people to sign up using your referral link
When I contacted their support I was told that no I can't spend WXT using the card, I have to exchange it for something else, when I asked them about the blog post above, I was told that it's old and outdated & at this time you can't spend WXT using your card, and that I can always check their FAQ for up-to-date information.
The FAQ does not answer they question "can I spend WXT using my card like your blog says?"
The only conclusion I can draw from this is that they are doing this on purpose, don't fall for their tricks.
Having said that, if you still think Wirex is worth trying, here's my link https://wirexapp.com/r/Tsuhna
EDIT 25.03.2022: Wirex support is now saying that their blog is correct & that "spending" should be understood to mean that once you have saved up $50 of WXT you can exchange it for another currency & spend that, I still think the blog is (purposefully-) misleading.
