No matter how is the market there are still people who continue to use Bitcoin as it is, a currency. They don't really care of its value.
There are already plenty of means to pay using BTC, I don't get why do you think the site you mention helps to pay or donate with the current market. I find it not relevant to the thread title.
idk, I just thought Wispay is doing something interesting, like give users a Paypal-like experiences. Which might be able to bring people who never had any crypto knowledge into the market. So it's kinda relevant as it was the first thing popped up in my mind when I was thinking about payment/donation with cryptos.
