Browsing a bit @Zapstore for apps I found these very interesting P2P apps for goods and services with Bitcoin.
NOT buying and selling BTC for fiat, but buying and selling goods and services FOR BTC.
I think this is how is Bitcoin supposed to be used.
For all those selling goods and services I am strongly recommending you to take a look at these apps. I am sure there are more apps like these on Zapstore and I miss them, some of them even for local communities.
