Don’t get me wrong, crypto definitely has its uses. But other than national or international transactions that I‘d prefer to be untraceable, from a European perspective, it seems to be too unwieldy for day to day use. At least for the foreseeable future.
I use PayPal because it quicker and easier than grabbing cash from an ATM or to pay online. I use Apple Pay, because it’s quicker and easier than searching my wallet. Crypto would ad at least a step or two to any of those processes. It’s neither quicker nor easier.
