The Slide app is now accepting Bitcoin as a payment method when buying gift cards in the app. To do this, you have to prefund your account with Bitcoin using BitPay.
It can take up to an hour for the deposit to be processed, so it might not be useful in a time crunch. One benefit of this though is that because you’re prefunding your account, you’ll earn 5% cashback from the Slide app as they offer an extra 1% on top of the standard 4% cashback rate when paying with funds you’ve already added.
eGifter already allowed you to buy gift cards using Bitcoin and other types of cryptocurrency, but it’s always good to see other places accepting Bitcoin payments.
