I use cryptocurrency every single day, I mostly use a middleman like Bitpay to process all of my transactions. So even though I might not be buying bread with USD, I used my Bitcoin to make the purchase. This makes it nice for me since I run my business in the crypto space, I can get paid from someone in China instantly and buy food at the store within 5 minutes. I love that about bitcoin, what about you?
unfortunately in my country there are no stores that accept bitcoin or other crypto as payment options so I can't use bitcoin to buy daily necessities, but I once bought electronic goods online using bitcoin as payment and I think in a very sophisticated era now bitcoin and crypto are very good payment options, especially for large amounts.
Marketplaces which are created on blockchain technology use bitcoins as their payment method but not much of the stores are accepting bitcoins as a payment source. There are very few countries doing so and hence it does not allow each of us here to transact with bitcoins to buy any commodity.
We can ofcourse use bitcoins for online shopping as we can see a number of online stores accepting cryptocurrency payments and it is only possible due to various payment gateways who accept cryptocurrencies like coinspayment, etc. We need more awareness about bitcoins so that peoples could also start accepting bitcoins locally with the lightening networks.
