It can be all - a method of transferring money, a method of payment for products and services, and a convenient way to invest while it's going up. There's not that much friction to exchange it for currencies. I just transferred a five-figure USD amount to an exchange, sold it for BTC, sent them to another exchanged, sold BTC for Euro, withdrew it on the other side of the world. All of that through two exchanges based in countries I've never visited. I saved enormous amount of money compared to just wiring USD -> Euro through my bank. For every bad story your read online there are hundreds of transactions that went perfectly fine, but people rarely bother to write about their positive experiences.
