I urgently need euros. Can you tell me if there is a way to buy them with cryptocurrency? I have USDT in my crypto wallet and I would like to exchange them for euros on the WISE system.

Of course, exchanging cryptocurrency to fiat and back can be very easy and also quite fast these days. And you can even do it online if you find a safe and reliable service that provides a profitable exchange of USDT to Wise EUR. Like, for example, this one https://nimlab.eu/exchange/usdt-tether-trc20-to-wise-euro/ .
