Long story short: Yesterday I posted on my Instagram that I was selling my gaming chair and a lot of people were interested. The fiancé of the cousin of my mother saw the post and came to my home to see the chair.
The funny thing is that he works with BTC since 2016 and he made a lot of money! We had a good talk about Bitcoin and I ended up selling my chair for BTC! (we talked more about BTC than about the chair lol)
I would never imagine that one day I would sell something for BTC!
