As in the title: How often do you use cryptocurrency (on chain, non-custodial) for payments.
At the moment, none. But i used to receive payments in Bitcoin at my previous job as an IT support analyst. When i want to spend my fractions, i usually search for sites that accept crypto, but it's challenging to find a reliable one that's available in my area.
If not so often or not at all, why do you think it will scale in the future and what will make you use it more often than today.
Bitcoin must become a store of value before it can be used by people as a currency. By then, i believe that layer 2 solutions should already be more developed to support average transactions. But it is inevitable that Bitcoin will one day become a store of value.
I am using cryptocurrency at least once a week for various online services, simply because it's more convenient and also more private, cheaper and faster than using regular FIAT options.
At the moment I'm only converting/exchanging bitcoin for fiat on the exchange when i need to pay bills and other personal expenses, but I've even used it to buy clothes from online stores.
