The Maiar app is another great option for paying using crypto. Via the Maiar crypto wallet feature, you can add funds and send them for payments via the app. You can use a number of different cryptos in your Maiar wallet, including Binance Coin, Ethereum, and Bitcoin. You can add contacts to the app directly from your phone's contact list for direct payments, which makes the whole process a little easier.
But that's not all the Maiar app offers. You can also reach different levels on the app for performing various tasks. These include inviting friends to the app, the number of learning stickers you earn, or the amount of eGold you own. eGold (also known as EGLD) is a crypto coin you can buy or earn via staking. And yes, the Maiar app also lets you stake!

You can then decide how much of your eGold you want to stake. Keep in mind that you need a preexisting amount of eGold (usually 1 EGLD) to get started in the staking process.

Electroneum is a solid option for people who want to pay for products or services using their crypto funds. However, it's important to remember that you need to own Electroneum (ETN) to make payments using this app.

Unlike the other apps listed here, Bottlepay is designed for only a few functions. You can trade Bitcoin for legal tender, or vice versa, add funds to your crypto wallet, and send or requests payments via Bitcoin. Additionally, you can make payments via social media using the Bottlepay app.
Just keep in mind that Bottlepay only supports Bitcoin as its sole fiat currency, so it probably isn't the app for you if you're more interested in using altcoins such as Ethereum, Litecoin, or Dogecoin.
You can also add contacts directly from your phone's contact list to make payments quicker and more convenient, connect your social media accounts for payments, and set up scheduled payments or trades. The app itself is pretty simple, but very useful if its features align with what you need.
