1. Speculative/trading/buying coins hoping to get rich.
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 bitcoin as a tool to invest, and maybe also speculative. And of course hope to gain profit when the price goes up. The price is irregular, it's one of the arts that I like and makes a lot of people curious. Bitcoin has not been able to be an exchange tool evenly throughout the world, but it still needs a process to convince many people. And it will be a revolutionary tool for transactions.
