This is really cool , one thing i dont like is the 24hours aspect, looking at PAYZA i like the idea but there are so many other ways to do this.
Personally i use https://spectrocoin.com/en/
they have a visa debit card that they send you and its really convinient , you can get payed in more than 50 types of cryptos. there 2 main coins are bitcoin and dash and when you send any crypto thats not bitcoin and dash it will be converted to one of those coins which you choose.
the best part it the load is instant, once you are ready to load the card you go on the website and you exchange the btc or dash for usd, euro or gbp (there is a gold option too) and you can use your cash with your visa debit card.
then there is
https://cryptopay.me/
ive seen others use this one and the procedure is similar but im not to sure cause i dont personally use it
There is https://bitpay.com/
https://tokencard.io/
https://www.bitwala.com/
https://xapo.com/
https://www.tenx.tech/
which are all new some work differently some spend pure BTC (which is a hasttle) and some use there own tokens.
So look around see what you like
