2. As a medium of exchange, currency to buy stuff just like you would for money.
3. As a means in itself to make money, i.e mining.
Also why did you get into bitcoin?
1. You were one of the first movers? You thought it was cool, interesting, you were here from the start?
2. Revolutionary ideas that it's going to change the world, banking system, etc.
3. You were just curious and then the more you looked into it, you saw how cool it was and promising(me).
4. Speculation, wanting to get rich.
I use it both as a medium of exchange, and as a means to make some money mining. It might not be much, but is a means of surviving the worst inflation my country has ever had.
I do think its a revolutionary idea, that will put an end to traditional banking. Sooner or later more people will "get it", but it is a long transition phase. I got really curious around 2013 when the crisis here started to get worse and I was looking for extra income. Unfortunately when I first heard of it around 2010 I didn't gave it the attention it deserved. But now that things got really bad, it is very hard to accumulate enough to do any investment. Most of it is spent in food and service bills.
I'm even looking for jobs online that pay with bitcoin because moving fiat money is nearly impossible without getting ripped off or scammed. Tho few people accept bitcoin here (mostly due to ignorance) it is possible to exchange small amounts for the week to buy food and pay things. We cannot exchange "large" amounts, because our fiat loses half its value tomorrow (and everyday gets worse). The "whales" (mostly people living abroad) that do, are buying back or spending it quickly (ie. trading).
