and one of them is my example which happened unexpectedly https://bitcointalksearch.org/topic/--5401052
and for other reasons in the country where i live bitcoin and other cryptocurrencies are not allowed to be used as a means of any transaction and only allowed as an investment so only individually i can use them and although purpose to invest for some reason but someday will use them and happen unexpectedly.
And it's all because of continuous development and growth and there will come a time when we use it and I believe that's because that's what it's for.
Congrats for that safe delivery of your wife. For me, the only thing that I bought with my btc is internet data. It was bitrefill, the site that I use. I am also willing to use my btc offline but so far no stores accept btc here.
